I agree with all the points you raised. Except for Immortal Hulk (I can't agree, or disagree on something I haven't read)
I didn't care anymore about the X-Books. Flagship ? Core books ? Satellite books ? I didn't care for years (except for X-Men Red, because of Taylor's Jean Grey. And the Art was great, despite too many artists change)
Now, I feel like the books are on the right track again. I feel like a fanboy again. Like you, I'm checking weekly to read the books. And yes, they have a direction, and they all (so far) feel differ nets. Each have its own "taste". And damn, it tastes very good.
