I can certainly relate to much of what has been said here.
Many of us still haven't fully recovered from the shock and sting of disappointment, as expectations fell woefully short, in the whole GT5 episode.
You know, aside from the points the OP makes, I have to say that the GT section seems much more critical of the upcoming GT title than it did prior to GT5's release. That might just be me, but I do feel like I've stumbled across more (valid) concerns and criticism for GT6 in a few days than I expected. I'm not sure what to think of that.
The difference is GT5 was following GT4, which was the best in the series, thus far.
GT6 is following GT5, arguably the worst in the series, even after the longest wait.
Now it's time to go through it all over again.
My expectations are much more tempered this time.
Statements from Kaz that he doesn't consider online important.
He didn't really say it was not important, but he did indicate that the single player aspect was the real core of the game.
Since this is the area of GT5 that suffered the worst, his statement on this I find very encouraging for GT6, as well as this:
He also indicated in one interview, that the severe imbalance of the PS3 made it extremely difficult and time consuming to develope GT5,
but they were much more adept with the system now.
GT4 was the last release on the PS2, and again was the best thus far.
Perhaps GT6, being the last GT on PS3 will be similar, and PD will go out with a bang.
I hope they pull one out of the bag. I'm not holding my breath though.
Well put.
