Hang on to your hat, dude.
Technology over the next 4-5 years (and probably beyond, of course) will explode in the digital musical instrument world. With the exponential increases in computing power and new compact storage technologies that are coming up, just think of the possibilities . . . much more realistic sounds, soft synths (maybe incorporated within hardware controllers), etc.
The coolest part, though, is that it will continue to get cheaper, too!
Wish I was 40 years younger!
