The video link below is Kurt Weigel's take on the new MSH RPG that's hit the online .pdf download sites now. Kurt does a good job of staying on topic, and focuses on MWP new version. There isn't a huge amount of comparison back and forth with the classic system, but I suspect a large part of that is because they are so very different. There were some topics I wish he'd spent more time on like milestones, but in all I'd say it's a helpful video review of the game so far.
I wanted to post it here because I haven't received my copy of the game yet and this was an additional source of information on it that will be helpful to those considering picking it up. I'd say that it's flavor is so different than the previous version, there will be people who love it and people who don't care at all for it. Much like classic coke and new coke (or pepsicoke), but fortunately this new game is much better designed and thought out than the previous example.
Enjoy!
