Patch 4.0 expected date?

[Maxion]

Hate to be a nitpicker, but wouldn't it be 3.4 something or 3.5 since the 4.0 will probably ship with cata? Nonetheless i'm guessing it will be 1m-3weeks before cata ships (I'm guessing late nov - dec)

Oh right, I may have been thinking about 3.9 with the pre-cata events.
Though we will get 4.0 a while before cata release with new talents etc like we got 2.0 a while before bc and 3.0 a while before wotlk. I may just be mixing up the time estimates for that with that of the pre-release event patch.
