I have a buddy whow orks for Samson. He gave me some lit. on the H2. Didnt mention a release date, but I will ask him when we can expect it to be released.
I use an H4 fairly regularly, and for me it works great. if you are on a budget, I wouldnt hesitate to buy this recorder. only downside is no digi-in. I can deal w/ the 2-XLR/1/4" inputs though.
