I'm thinking more like playabl PvP maps. the Asura starter area, "class 8" or the Sylvari reveal.
Too much info is not released for there to be an open beta this summer.
If it is a release date it should be several months off so they have time to get GW2 ready, its just not yet unless they hid alot on fan day. I agree if its a release date its more likely Blade & Soul.
Is B&S even in beta yet?
EDIT: Okay let's look at the facts here. Arenanet loves europe because they got a lot of their sales there. They showed off a GW2 for the first time there and unveiled the necro there too. So when thinking about it along these lines I'd wager that this might be a beta date reveal for GW2.
On the other hand, this might be the chance for people to finally get their hands on Aion patch version 3.0 or whatever that epic vision trailer was about. Or it could be them just showing off B&S for the first time in Europe.
