You shouldn't have any issues running it, but personally I'd wait a few weeks. Wreck doesn't want to put out another preview patch too soon, but Sub ported the GE instruments over and I ported the MIDIs, so you'll have GE music as well, and I'm going to be fixing up the path networks for the other three stages so that they can be played with sims. As cool as it is, only playing Egyptian gets old after a while, and even that one's not perfect yet since they can't follow you through a few areas.
