I know that's the likely timeline. My hope is that because consoles today look a lot more like PCs than they did in 2013 (or earlier during development), that it might be sooner, plus from leaks we know that development appears to mostly be happening on PC (I mean for real builds not just engine tools and cross-compiling).

But I realise that's just hope. It's probably also about business priorities and PC is just not a huge market.
