From ArenaNet’s Sunday blog posting:
“We recently finished our first closed beta test, and we’re now ready to hold progressively larger events. In February we’ll invite select press to participate in beta testing, and in March and April we’ll aggressively ramp up the size of our beta test events so that many of you will have a chance to participate. And of course, this all leads to the release of Guild Wars 2 later this year.”
My guess at an April launch could still conceivably happen, but May now seems more likely. Press being in the February beta should lead to new videos, screenshots and other coverage, anyway.
