ok GT6 for ps3 just makes sense to me. With the ps3 install base the game can sell alot of copies at full price making Sony some much needed money. then GT7 coming a few years later on ps4 will have a larger install base to sell to meaning more full price sales than if GT6 was a early ps4 game. also GT6 wont be hindered by a lack of knowledge of the new ps4 tech, im sure come GT7 they will have had time to make a great ps4 game after learning how to use it to its capacity (maybe not its capacity but you get me). i can understand the arguement though that GT6 on ps4 could push ps4 sales.
Also want a REAL GT on my Vita, the PSP game was disappointing.
