It seems we won't be seeing Polyphony's next game for a while.
There's a lot more in the interview.

Theres been no mention of any more Gran Turismo and were still waiting on a date for The Last Guardian. Is Tokyo going to shed more light on this, or are we going to wait a little bit longer?
Yoshida: Id say it could be a little bit longer. As far as the Gran Turismo teams concerned, they are still working on updating the games, so theyre just shifting to the designing and concepting phase of the next project. Its going to take a few years.
The Last Guardian team has been making progress. Its been very difficult in terms of seeing the progress: not as fast as wed been hoping for, and the team has been under big pressure. But were still making progress, so Id like to continue to support and keep waiting for great news sometime in the future.
