Oh hey, guess who still owns the trademark to Crash Bandicoot? I'll give you a hint, it's not Sony Computer Entertainment America.

I think some people need to let go of the idea that Sony is buying by the Crash IP and releasing a new game. It's not out of the realm of possibility and it would be insanely awesome news, but it's not in the cards for Sony right now. Maybe at some point in the future, but I'm not expecting any sort of announcement from Sony about Crash any time soon.
