For me, it's not so much about having one more gear ratio. It's more about reliability and modern design.
The 5 speed box in my WRX feels great, but the syncros are not up to par. Grinding in first gear from a dead stop is not acceptable. Having to double clutch and rev match when pulling into a parking lot is kind of fun for me, but I would be uncomfortable allowing my S.O. to drive it for this reason, again unacceptable in this class of car.
Stories of broken gears abound on the WRX. The 2.5T will be making at least as much torque as some of the mildly modified WRX's which have busted gears. As much as I like the Legacy turbo, I will not buy one until I am convinced that they syncro issues and gear strength issues have been resolved.

Isn't the 6 speed alot more than 600 bucks additional? I've looked around for just gear sets and the 6 is like in the 3,500 range

Subaru 6 speed is made by Subaru internally and the problem is, they can't make enough due to the capacity of the factory.
From what i heard, thats why Legacy doesnt have 6 speed right now.
Probably 6spd legacy will come out later once they solve the situation.
If they do S402 or Legacy STi, those will be 6spd for sure I think.

does anyone know if the 5speed auto will have a speed limiter like on current Subie Autos? Or will I just have to get the MT?

Yes WAAAY to tall. The rpm drop from 4th to 5th is excessive for a performance car, especially for onw with only 2.0 liter displacement and it's peaky power curve. A 3 liter V6, or 4 liter V8...sure, it'd pull the gear fine. But for the 3100lb WRx running its little 75mm crank and big ports, it needs a steeper 5th. The STi RA box would be great. Too bad that Subaru caved in to what the "mass market" wants and not what people like myself really want. Im my opinion, I would've just shortened up the final drive a bit and all the gears would be closer and the motor would be even snappier.

AND BTW: the engine would NOT be working HARDER in 5th. The tall 5th that we have is taking leverage away from the motor and giving it to wind drag, rolling resistance, and weight. Think about what happens when you hop on a multi speed bike and try to pedal with too high of a gear, your legs want to die. If we could bring the final drive down a little bit, it would lessen the actual load on the motor and it would become more lively. I would rather have the motor pull harder at more usable speeds than 85mph +. When I was in the 'hot rod' VW business I was amazed at how many people would think that going to a Bus 4th gear (0.82 vs 0.89 for the Bug) would improve performance. Some peple even coupled this stupid decision with a 3.88:1 vs. the orig 4.12 or 4.37. Really dumb idea on an air-cooled car (especially). You're slowing down the cooling fan AND increasing the load on the motor.

For more info you should read about gearing a turbo car for performance in AG Bell's book "Forced Induction Performance." It clearly explains the problem of the WRX's (even the STi's) turbo lag problem and its wimpy gear ratios. It can all be explained at worked out with percentages from ratio to ratio.

Do you have a reference for this? I am very interested because when I sent SOA an inquiry as to how the 5 speed was "reinforced", this is the answer I got:

"At this time, we do not have specific information on features, options,
or pricing for the 2005 Legacy models. We should have this information
later this Spring, as the vehicles are expected to be available at
Subaru dealers in June. "

I will inquire again, but I am not hopeful that SOA will be any more helpful this time around. If you have a real source backing up your claim, I would be very interested. The poor quality of the syncros in my WRX is the only reason I would not consider the Legacy GT.

It’s not like a 2WD car where traction is going through one or two wheels and then up in smoke, the WRX has 3 traction surfaces (the open front + viscous center and rear differentials transmit power effectively to a minimum of 3 wheels) which places much greater loads on the internal components of the transmission (which few owners that destroy their transmissions understand.) Previous to bringing the car to the USDM, the rate of failure (including high-output STi models with the virtually the same tranny) was MUCH lower, which shows how abusive the American crowd is in general.
That's all fine and good, and I do agree that abusive launches on cars with power modifications are an explanation for a large number of instances where first or second gear has broken. But this does not explain the problems I am having with the syncros. I do not do drag race launches, and if I did, why would that adversely affect the syncros? My buddy has a 1986 Audi 4KQuattro with over 200K miles on it's transmission and he bangs the gears so bad it makes me cringe, but the tranny works flawlessly after all that abuse!
Bottom line: My car grinds first gear from a dead stop, and has done so randomly (usually when hot) since ~20K miles. I will not buy another Subaru until I am convinced that this design defect has been fixed.

BTW, I live in San Jose. Thanks for the compliment, it seems there are a lot of California bashers out there. For all the beauracratic problems we suffer, the weather and natural land features make it all worth it.
