I have my U2 as well as other lights that have Crees and I still like my U2. I like the beam pattern and it is PLENTY bright for what I need as well as useful. Just because something is newer doesn't make it better. I don't understand why some people are so quick to poop all over anything that isn't the "newest, brightest, whatever, blah, blah, blah". If that is the opinion and point of view a person has, they will never be happy with anything. If you want to be technical and realistic, as soon as a new product comes out, it is already obsolete because the company that turned out that new (obsolete) product is already at work on newer, better, projects, even as they go to SHOT show. I would be willing to bet that Surefire has projects going on RIGHT NOW that make the UA2 and UB2 "obsolete" and the UA2 and UB2's aren't even ready for retail purchase yet. I love my U2. I LOVE my A2 Aviator as well and I am acquiring a second one of these "obsolete regulated incan/5mm LED hybrids" because I love them and I use them a lot. The way I see it, if you don't want to own an obsolete light or any other obsolete product, don't buy anything at all.
