You aren't getting GT7 until 2022 at the very earliest, you'll get a single player expansion for GT:S and 4K 60fps more VR etc and a next gen "complete edition" for 29.99. It's a GaaS that's performing well (Sony's only one?), is well respected for its mechanics and is basically next gen future proofed in terms of its assets. Sony would be mad to cast it aside to push out a new one when cars and stuff are still being added.
