My guess is that Chris will come in and say something like: There is no public timetable atm something something potatosallad.
Personally I don't think we will hear much groundbreaking news even during 2010. I guess that there will be a lot more conceptart atleast xD And MAYBE some alpha footage. But showing alpha is NOT very popular in the gamingindustry. Uhm...closed beta... at the earliest I would think beta will come around 2011, probably late 2011. Release - An early guess would be 2012, but you can always add some years to that :/
Im being a bit pessimistic about the timeframe becouse thats how it usually is in this little world
BUT this is just my guessing and these guesses are optimistic at the most >,<
