So I have had a day to play with MASCHINE 3.0
First impressions: 
LOADING PROJECTS is way faster. 
Bouncing not only is more streamlined that drag and drop audio/midi, its way faster. 
It actually collapses your track and its fx/plugins into one audio track. Where as before you would have to go back and delete the original track / plugins etc etc
this is a huge time saver and CPU saver. 
Clips view is much easier to see and track. Some visual improvements were made I noticed. 
However, I do miss the subtle gray shaded 3D interface of the old GUI / it was charming. 
Everything doesnt have to have a flat looking interface like APPLE or ABLETON, people get sucked into this trend
