Ghostcrawler posted a bit this evening on the philosophical direction Blizzard is taking in Cataclysm in three important areas:

The discussion originated from a mild QQ post about what the poster felt were the flaws in Cataclysm, and Ghostcrawler took that opportunity to clarify a few things that the community has been talking about since the initial announcement at BlizzCon 2009. Chief amongst those is that they are specifically designing talent trees now with an intention for there to be 5 to 10 talent points that can be spent where the player wants -- and that talent guides like you find in WoW.com's class columns will only go so far in the selection of the idea talent tree; the rest of the talent selection will be left up to the individual user.

Of course, this information isn't exactly new, but it's interesting to hear some of the refinements of it all as Cataclysm's development progresses.
