I hadn't even heard of it before. Seems UPLC is a brand name - did you just come from a marketing presentation or something?
I agree with Borek, it's just an incremental improvement on HPLC (which has naturally been improving incrementally for years regardless). I wouldn't call it a new tool or method, and I doubt it's a game-changer at all. It's a more efficient method, but not fundamentally different from HPLC. I'm sure the PR folks from Water Corp are of a different opinion, but I see it as an incremental improvement in technology which will give an incremental improvement in research, but it's not likely to open up any new fields or such.
AFAIK, the big current tech trend when it comes to e.g. protein purification are the highly automated so-called "high-throughput" methods.
