Didnt polyphony make the PSP Gran turismo aswell in those years? They might also be working on a Vita one. They also make concept software for car manufacturers and car expo's. They dont do videogames only, and Gran turismo is still a beast in sales, so it might take a while but its worth the wait somehow (personally i grew bored of the series by GT3 though).
For me the biggest shocker is they havent released any more Ape escape installments. Thats a pretty fun game.
