At OWU the Oceanic rep told me March, but one of my LDSs says late summer. I'm actually trying to nail this down because I'm looking to by one for myself and Mrs. FoShizzle before we hit the water this year. Failing the VT4, I'm looking at the Suunto Vyper Air. I would like the dual Alg, but I'll be diving more conservative most of the time anyway.
Edit - Another LDS tells me "sometime this summer", and a third says he just got back from Oceanic where he was told 60-90 days. I don't know how the dive industry is with release dates, but most of the industries where I've done this kind of research, if they don't have a firm date 60-90 days before release then it ain't gonna happen in 60-90 days. I am glad they are taking their time to get it right, but I need a new computer this season not next so I'll be getting pricing on the Vyper Air. Any Oceanic people reading this don't be alarmed, I rely on my computer to keep me alive so if you rushed it to market I wouldn't buy it anyway. Do it right the first time, sounds like a great machine so I have know doubt you'll enjoy some nice fruit.
