If they stick to just remakes, I'm sure it'll sell like hotcakes. I'd gladly pick up banjo Kazooie and Tooie with updated graphics and the same gameplay.
But I don't want them making a brand new Banjo Kazooie game, especially after playing Crash 4.. it just didn't feel enough like those original games. The difficulty was ramped way up, the levels dragged way too long, and the story and characters didn't feel the same at all. I don't think they understood what made those games so popular.
