It's really, really, really hard to say what the Galaxy S III will have since there are only unsubstantiated rumors and no hints from Samsung yet. If it's released overseas this summer, we probably won't see it until the fall in the US, so keep that in mind if you need or want something now rather than in 6 months.
The Skyrocket has excellent specs and should hold up well. The Galaxy Note is a pretty unique and powerful smartphone that's not likely to be usurped any time soon or even this year. With LTE, a huge display and an active digitizer, it's hard to beat if you don't mind a very large phone.
