what do you all think of the manifest destiny saga, miniseries, and all the one-shots ?

It's good so far.  I really like Bianchi's art in Astonishing.  It reminds me of Jim Lee, but more stylized.  My only complaint is that it is going to be a part of Secret Invasion, which I can't stand.  This entire crossover is just an excuse for them to redo storylines that did not sell well. 

yeah agreed, but then again secret invasion has been planned well over 3-4 years ago, around the time House of M was being published. So I doubt they just recently decided to make every book tie in to the series due to recently bad storylines.
