Sorry I've been out for a while folks; work kicked up again.
Yeh, this current Hulk is still pretty open for any direction. There is some contradiction in his showings, but they have been minor (such as having Hulk resist energy that can melt Adamantium in the fight with Thinker and having it once again stated on panel that Hulk's strength increases with rage and has no limit; and then turning around and having Iron Man hold his own and Hyperion do the same. The saving grace being that these were minor scuffles with no true motivation for Hulk to rage out).
This current Hulk may not be Savage (which is what we are pretty much all hoping is the case; Savage has been used as a defaualt one too many times for my taste); but by the same note, he may be a new Hulk altogether.
If Marvel is trying to meld the movie-verse with the 616 to bring in new readers, then this Hulk will likely be more akin to a "Gravage" type with few words and high showings of super-fast brute force. The healing factor and amping may take a back seat to higher base strength and super speed. We'll have to wait and see.
Regardless; the writing is good and Banner is getting his due. This run will add two things to Hulk (not really add, but cement in the minds of doubters) - 1. Hulk can be fast. Very, very fast. His super speed on panel will soon have a flood of feats to post scans of. 2. Banner is indeed one of the smartest beings to ever walk the planet, and his tech has the potential to save or destroy the world.
This is nothing new to many of us; but it will now have a ton of back up evidence when the misinformed start ranting on the v.s. boards.
In time, we will see how intelligent this incarnation of Hulk is. And in time, Hulk will have a new writer that has the mythos of classic Hulk (stronger with rage, no upper limit, incredible healing), and a nice dose of superspeed and Bannertech cemented into this mythos.
I suppose what I'm trying to say is that regardless of how this run turns out; Hulk will walk away faster, and Banner will walk away smarter (in application). Waid has given us speed and intellect with strong on panel feats to back it.
So, IMO, the future looks good for big green. Be it now, or down the road when the next writer takes up the legacy.
