I'm curious if anybody has made this switch yet, and if the improved playability justifies spending the money. I'm a little bummed at forking over another hundred bucks because I just bought RA a few months before the Play version came out. But if it noticeably improves the legato and other expressive playing, I'll have to bite the bullet.
I have NI RA and will be upgrading to PLAY now that 1.2 is working well. I have just switched to PLAY SO Gold and that is working very well (now that I've upgraded to Cubase 5). Might as well take advantage of the cheap upgrade prices at the moment.
