Actually it is not "Strawberry", but "Titan". But if you look at it objectively, Blizzard confirming that the code-name for their new MMO project is "Titan" is pretty much a non-event. "Strawberry" would have given exactly the same information, which is none. It is not even the name of the final game, just the name of the project. The game will most probably have a less generic name, as the term Titan is already overused.
Much of the excitement over the official Titan confirmation comes from the fact that the name was leaked as part of a Blizzard production schedule, and that some people now believe that if the leak got the name right, the rest of the information must be true as well. That would mean the next WoW expansion in 18 months, and the new Titan MMO in 2013.
I would be very careful with that sort of jump to conclusions. Even if the leaked schedule is real, Blizzard is not exactly known for sticking to schedules. Basically in the best case I'd consider that as a penciled schedule, which in all likelyhood will be much delayed in reality. Note that Blizzard already after the first expansion said they would work towards releasing expansions once a year, but still got their third expansion out only after 6 years. So my money is on the next WoW expansion end of 2012, and "Strawberry" being released in 2014 or 2015.
