BTW, over on the Paizo 4e boards, I learned that Nicolas Logue did the fighter chapter of Martial Powers, as well as some of the PPs for the other classes.
...I don't actually own any books by him.

How is his stuff? (Scanning through the 3.x books I kept due to their awesomeness I realized that Ari wrote some of my favorite 3.x material)
In addition to feats, I hope that there are more stances. I particularly love those types of powers. Also, for the Beastmaster ranger build, I hope they include all of the stats for the normal animals that did not appear in the MM or AV.
I want more encounter or at-will stances. I like the powerful fighter daily stances, but some that are more Bo9S'd be rad (In my homebrew 4e game a couple months ago - before the pdfs were leaked - I allowed L.2 Utilities to be (what I thought were) weak buffing stances). While I won't see them in this book, I think stances for non-fighters/swordmages'd be cool. As far as the beasts go, I think they'll have a few 'typical' ones... and then say 'Look in the AV or MM for more!'
I REALLY like that idea of a grab-based fighter. It reminds me of... some German fencing I once skimmed over on TEH INTARWEBz a few months back. Things about engaging the enemy in melee and then wrestling them to the ground.
I gotta' say that I still feel hand-jiving can be a free action. But, clarification'd be good.
In regards to the non-(or partial-)divine paladin... hrmm... I don't think they're going to do it. I'd like to see it.
Actually, I take that back. If they make generic classless/multiclass powers - sort of like the spellscarred - that are of a physical variety it could work. I know I've seen a bunch of ideas in the houserules section on common combat maneuver powers. I think something like that would be quite excellent.
...actually, I think if I don't see anything like that in martial power I may have to try my hand at making something.
