Ooh, that does look really good!
But yeah, at this point there are so many good games out there that I feel silly for buying one at full price when they are likely gonna have to patch it a few times upon release anyway.
I'd be way more likely to do it for a smaller game than an ambitious one with open world gameplay like this one, there's just too many variables to control for during development/QA/beta given the market pressures.
