Virtual PC version 6 and new Mac OS 10.5

Does anyone know if there's a problem (or will be) running Virtual PC 6
with the new OS coming out? I'm running OS 10.3.9 now and am thinking
about upgrading to 10.5 (actually I was going to upgrade to 10.4, but
heard the new one is just a couple of months away). Any Virtual PC aces
have any thoughts? Thanks!
