They seem to be keeping the core rotation - It's just the Leaden Fist Bootshine - Dragon Kick and repeat Perfect Balance window is being replaced with something more complex and flexible with better uptime - The end of Perfect Balance also puts you into Form Shift, which is a great change.
Assuming that first Blitz in the trailer is an AOE Blitz and the second single target - In my opinion it beats just elixir field (which is now one of the smaller Blitz's) and enlightenment on cooldown with the 1,2,3 combo.
The 40s 2 charge PB means we get to use that way more.

The loss of positional requirements on Twin Snakes and True Strike isn't too big of a deal to me, lets you flow from flank-rear more comfortably and mix up when needed and will generally help in fights with lots of boss spinning.

Anatman is still there in the demo they did - Interestingly Tornado kick is gone but they didn't mention it - Also Arm of the Destroyer is gone - replaced with a similar looking ability as Tornado kick so that might mean Tornado is a AotD replacement now and is AOE.

The Fist Stances are also one button now, so maybe we get slightly higher move speed and the damage buff at once?
