i just got mail from bada developers stating the event to be held at MWC2011.

Date: Tuesday 15th February (09:00~17:00)
Venue: Hall 7, Fira de Barcelona

The bada website has more info about what they'll be talking about, but in short it looks like they are discussing bada 2.0 in more detail. if you are selected, you will be invited to apply for a free pass (EVP) in MWC2011.
