From what I had read we can expect the ability to "copy single regions from Prime and paste them as a picture in any other application" - explicitely mentioned is pasting into M$ Word. I am not sure if they have vector graphics in mind, though. They should, of course, especially given that the major product of PTC is a high end CAD software. So lets hope on improvements in Prime 0.3 (sorry, but its too hard for me to accept it as 3.0).
Concerning plots I don't know of much imporovements:
- improvements on countour plots (whatever)
- matrices are plotted as waterfall plots as default
- better look and feel of axis border values
- limit of 500000 datapoints as in Mathcad 15 and below (In Prime2 only 50000)
The info is from a link somebody posted here

Anybody more details about Prime3?
