Good news for X1000 owners! It took a while, but audio got there at last, one more tick in the checklist...

Price is one thing, availability is another...
But maybe the "X2000" will feature the same AMD SB600 southbridge? That would make sense in several ways; existing drivers could be used (a big plus given how long time it took to actually develop whats here now) and that A-eon probably have some surplus stock to use.
So I'd say that this is more than likely (in fact, anything else would be strange)...

There's no audio connections on the Cyrus boards so they must be thinking of using PCI/-e cards.
PA6T lacked SATA and USB which are built into the P5020 so it wasn't really necessary to have a southbridge this time around.
