-Even more miniatures-centric? Check.
Not good, IMO. I want the opposite, with minis decoupled from the rules (i.e. you could still use them, but the system doesn't assume them).
-Much smaller bundles of game info, packaged and sold separately? Check.
Not good, IMO. Sounds like what I don't like about CCGs and collectible minis games.
A plan to possibly sell off RPGs entirely? Check. (Apparently only miniatures and Magic are making any money for WotC).
This might be okay. Personally, I'd rather see the D&D brand in the hands of a smaller company. I know some disagree with me, but I haven't liked the direction WotC seems to be taking the game.
I seriously doubt that I'll buy 4E. (Heck, I never bought 3.5 -- I just house ruled things like Haste, etc). I think it's likely that 4E will cause the market to fragment quite a bit, which I don't view as a necessarily bad thing. I think some will move to 4E, but quite a few will stick with 3E (more than stuck with 2E), and others will gravitate towards OGL systems like True20 and Castles & Crusades. I think third-party d20 companies see the writing on the wall, and are looking for additional baskets for their eggs. Green Ronin has MnM and True20, but even their other offerings (e.g. Freeport) are going to be offered with stats separately, so you can use the stats for the system of your choice. Mongoose is coming out with Runequest. Malhavoc has AE and Iron Heroes, and now Monte is shipping his magnum opus and moving on to opportunities outside of RPGs; I'd bet that 4E weighed into that decision, to one degree or another.
I guess I "jumped ship" when I didn't go for 3.5, because I think the only WotC product I've purchased since then was Red Hand of Doom (although I bought a LOT of stuff from Necromancer, Malhavoc, and Green Ronin). These days, my main game is C&C, but I still play 3E, on occassion. It'll be interesting to see what happens.
