Not yet, no. Matrix appears to be operating under strict radio silence at the moment regarding DW2's development and beta-testing.
Erik commented last month that they were currently aiming for a July release, but that that could easily change (and I suspect it will -- I'm still betting on an autumn or even winter release). Either way, I'm guessing it will be at least a month before we hear/see anything more, if only so that Matrix can avoid their promotional materials being buried under the news cycle of Nemesis' release.
