I'm going to get so pissed if the delay is due to Sony forcing PD to add useless features for PS4 Neo, 3D, VR or whatever. Or PD being PD and they're trying to shoehorn a half baked feature that no one ends up using (like the GPS Visualiser - I'd love to know the % of user that actually used it in GT6).
For those of you expecting the game to be more polished at release, it'd be wise to temper your expectations. A delay this generation means "we are struggling to put out a game in working order" and not "the game is done and we are just making it better". Driveclub, PCARS, Assetto, SLRE...need I say more?
For me, I couldn't care less about the delay to be honest. I'm already lukewarm towards GTS after trying out a demo build. This just means I get to hang on to my $1000 a bit longer as I don't need to rush and buy PS4/G29 this holiday season
My only regret would be I'm delayed from playing Driveclub again, but whatever. More time for Assetto for me
