As I stated in other threads, and in agreement with the sentiment of this thread, Driveclub being pushed back to "early 2014" is not really going to hurt Sony. The game was barely on the radar as far as preorders were concerned though I suspect a fair portion of that had to do with the free PS+ Edition. Though where I differ with the OP is how it will affect Driveclub itself.
For starters, I don't think Driveclub was ever going to be in a position this coming holiday season to compete. Look at the games launching; Assassin's Creed, Battlefield, Call of Duty, FIFA, Madden, Need for Speed, and even Sony's own Killzone which was already hogging the spotlight. It's very hot competition this season already. I suspect that some X1 exclusives will find themselves having similar issues thanks to very popular and typically high-selling franchises releasing all at the same time. So releasing at a later date, even outside of the holidays, may prove to save Driveclub from being crushed under the weight of so many high-profile games.
It also depends on how the finished product looks. This may actually help Driveclub in the long run because if the game was delayed due to Evolution Studios not liking how it was going to be for its initial release that tells me that there is a good chance the consumers would have reacted negatively to it as well. If this delay allows them to get the game up to the 60fps mark like they've been shooting for as well as maybe deliver on some content that they may have had to scrap, I think delaying would be considered for the best. It could be the difference between releasing a game that gets negative reactions or positive ones. Even though it will be outside of the holiday sales surge it will still be in the launch window. A time when gamers are very hungry for new experiences.
As far as Sony's retail exclusive lineup for 2014, I don't think it will need much help. About 8 first-party published games for 2014 have yet to be revealed, some of the Japanese third-party exclusives will certainly make their way West, and in the meantime there will be loads of Indie titles to choose from and some that have turned heads like Rime and Shadow of the Beast. I do have a feeling we will get word on a couple PS4 games coming next year at the VGA's this December.
