I think the book's too large for anyone to get a review out yet.
I will say that there is quite a bit more changed than most of us were initially led to believe. There's nearly two dozen new skills, or major modifications of older skills, perks and talents.
There is a new powers: Healing.
Many powers now have "adders" ( small point additions that slightly change how they operate).
Aid, Change Environment, Entangle, Flash, Force Wall, Hand to Hand attack, Life Support, Multiform, Shape Shift, Stretching, Summon, and Transform are just of few of the powers that are now somewhat different.
Sense effecting powers, such as Darkness or Invisibility, now have different costs if they are being used against Targeting or non-targeting senses.
Advantages and Limitations have been reorganized, some altered and new ones have been added. Mega-scale is one of the new ones. Damage Shield is one of the altered ones.
Many of the Disadvantages have had other categories added to them (Hunted, for example now has a Public Identity bonus).
There are new combat maneuvers such as Rapid Fire (allows you to attack one or more foes with a ranged attack more than once per phase) and Sweep (which works as before but now allows you to attack a single target more than once per phase), as well as some older maneuvers which have been changed (Haymaker).
There is now a rule called Multiple-Powers Attacks which allows you to use more than one offensive power against a target per phase.
There's quite a bit more, but that's all I can remember off the top of my head. Over all, I like it quite a bit. There's a lot to digest in the 374 pages, but almost everything I've seen makes the game better.
BTW: I think the Great Linked Debate has been answered.
