I just ordered the biab 2010 and was informed that I just couldn't upgrade for the realtracks 67 - 82 and realdrums 27 -29 in a megapack, but had to upgrade to an ultrapack, because that's the only way I could get the new realtracks, as well as all the realtracks that I just purchased in September, or whenever biab 2009.5 came out... Had I known this, I would have waited till December.. Anyway, not horribly terrible, but I really don't need a hard drive with everything I already have...
