Could We See WotLK Talents Before the Expansion

If you were around before TBC was released, you may remember the huge excitement when Blizzard revealed the new extended 51 point talents trees before the expansion went live. So one can't help wondering if Blizzard intend to do it again this time around.

Well, someone asked Blizzard on the official forums if that's what they planned to do before Wrath of the Lich King goes live, and Bornakk, in typical Blizzard style, didn't commit himself either way, but he most certainly didn't rule it out:

Things like this are always possible, but information and details on it will wait until we are closer to making it happen (if it does happen)...

...This is something, no specific thing, that is a maybe or a possibility and not a definite thing in the span of multiple maybe happenings which occurs before the positively going with things...

...Generally speaking spells and abilities may already have nerfs planned though before they are publicly announced as we may not be happy with how something is functioning.
