Diablo 3 has left a bad taste in my mouth, I don't really feel like playing another beta anytime soon if you catch my drift.
I immediately pre-ordered a 4-pack when it was available on Steam a few months back.
I'm glad that Runic decided to hold off on release until the game was ready.
E: You also need to realize that these are pretty much indie-games, but the "end-game" concept is spot-on, with lots of awesome features that haven't been done in games, at least for a long time. I'm very hopeful that TL2, being a larger production than the original, will be epic and I don't use that word lightly. I think it'll push the genre forward, as opposed to going backwards to generate more money with less work.
