On PlayStation Share, I proposed the idea of expanding Gran Turismo TV from GT5:P into a full application as a part of PS Plus, one that would be updated monthly with new news, trailers, interviews, etc. It could people a GT fan's one stop shop for the latest news in the world of racing and GT.
It seems to be getting voted down by GT haters, though. It's barely maintaining a positive rating. =(
