It is following GTA 3 in sales

and trust me GTA 5 will sell like GTA VC

& GTA 6 will sell like GTA SA again

and yes I believe GTA 5 & 6 will be released this gen

maybe with different names like SA & VC had

But does that really count as GTA 5 and 6? It seems like they only add a number if they change the game engine.
