Looks like they're not out yet.
The P7800s are though.
Are you sure you want this set? I know that creative's megaworks and gigaworks sets are nice, but I think the quality on their lower sets is kind of mediocre.
Speaking of megaworks... ecost has a refurb 6.1 megaworks set for $99 + shipping (which ends up being about $150) if that's in your pricerange.
