The way the devs were talking at Blizzcon, this probably won't release for like 4-5 years.
For folks drawing similarities to D3.. it's similar to D3 in terms of being an isometric ARPG, but the skills, movement, and a lot of the rest looks v different to me.
D3 right now is all about maxing your shit out to 1-shot everything with massively overpowered gear sets and buffing your movement skills so you're always blasting past everything. The D4 gameplay looked a lot more sedate.
The cinematic was pretty cool, but I was very unimpressed by the gameplay trailer. Contrast that w a gameplay trailer from Lost Ark, which I thought looked dope as fuck and would play immediately if it were available in the US.
Lastly, the way they're talking about PVP sounds just as retarded as the way they always talked about it for D3 -- "PVP areas". Like, what? This sounds like you just go into an instanced small battleground w/ your buddies to bash your heads in. 1) I'll be shocked if this is balanced. 2) What's the incentive to do this, rather than keep grinding your character in PVE? 3) Taking away the danger element of other potentially hostile players makes a gritty looking game like this be pathetically soft.
I dunno, I want to like this game, but I'm very skeptical at this point.
