Free climb is interesting. I watched the interview but I'm still not sure if they mean AC style or something else.Its gonna be something like AC or BOTW. You can climb everything anyways.
Also I'm feeling less disappointed about this news now. As I said about Horizon before, it would be a huge hype booster if GOW and GT7 were next gen only and would possibly result in some marginal gains in their quality (e.g. removal of shimmying through gaps in GOW) but its probably not that big, otherwise they would have cancelled the last gen versions. The games will still be as good as they were ever going to be.
Sony lying and being shady is the sucky part, but it is what it is. Horizon still blew me away with its graphics, GOW certainly will too. We just might not see some crazy gameplay leaps like with Ratchet, but that's okay, we're still getting good advancements like all the new traversal & massively improved melee in Horizon.
