Mike,
While I wouldn't say it's definite that I'll upgrade ( only because I'm a real try before I buy kinda guy ), if I were a bettin' man.. I'd play the odds that I'll be owning that ES pretty soon after it comes out..lol..
I usually don't get too excited about future releases, ( I'm definitely a PA80 guy but I'm only mildly interested in the PA1x, and I wasn't in a rush to see the PSR2100 ), but I have to admit I can hardly wait to see this ES and get it in my hands. I jsut hope the OS hasn't changed drastically. It took me quite a while to figure out the Motif's OS.. pretty steep learning curve it was for me.. but well worth it.
Cheers,
AJ
