If Toyota can pull off this IS430 or IS500 thing into reality, I don't think a V8 would be a issue for them to sell new Supra. It would have outdone the rest of the competition a little bit more with higher price yet still reasonable. I can't remember what was the name for the 280hp+ wagon on sale in Japan which smokes Legacy. From what I recalled, it is not cheaper nor competitve in price with Legacy. It was a bit higher. However, I do not believe that Toyota is going to heavliy tuned its 3.3L because that will be too much like Honda. 287 from 3.5 is still decent but 280 from 3.3 is somewhat a little bit high for a nice torgue. (I am just guessing) It will be very unlike Toyota to me. However, 1 thing for sure is it will be very sport car like how Toyota turns MR2 into MR-Spyder. I don't think it will be going like a super GT as it used to be.
