I'm happy about this, and I wish them the best. But I don't understand why they bothered announcing it this early.
I still have memories of waiting years for the first one to come out because it had been announced at a very early 2000 E3 expo (01 / 02'ish), a solid 6 or 7 years prior to release (it was released in 2007). It wasn't due to come out in 2007 originally of course, it suffered from multiple delays (and leaks, too). It was a very tough road for them to get that thing out. And it was absolutely painful to wait for it. This time the gap is lesser by comparison, but I still don't understand why even announcing it if they're probably not even sure they'll have the manpower, and of course the money to keep working on it for the coming three years; much less anticipating the absolute best without a single delay in between.
I suspect that there's going to be long periods of radio silence as well.
Anyway, I'm saying all this simply because it's the same (or mostly the same) team from GSC, I just hope that this time things will work out better for them.
