Well, in the last live letter they said they will be hosting approximately 1 live letter each month up until the release of 2.1. That sounds like quite a few months to me... Also judging from the myth cap, people wont be reaching full myth gear until maybe 2 months from now. At that point we should start expecting the release imo.

I have to admit i personally feel like SE is toying with their customers, intentionally sprouting the idea that 2.1 is going to be released very soon. If it was going to be released soon, there would be a date announced for it. Atleats thats what my logic says... I would expect the release around february or even march to be honest. Just my hunch, nothing more.
