The draw for GT5 Prologue, to me, was online play. That was the big leap over previous GT titles. Sure, there were many other improvements, but that was the big one. What could be the reason for me to pay for a GT6 Prologue? Especially on a new system? I'm not sure I'll get the new system anyway, certainly not for a game that doesn't have huge new features. If GT6 is realeased early in PS4's life, maybe I get it...if the community is still interested in it. I guess it depends if any other racing games are released on PS3/4 also. So many variables.
