According to some members at lovelockandload forums, some of the titles on MYA's list are licenced to some other companies already, and for some the rights owners won't licence to anybody.
MYA's upcoming Horrible (Rosso Sangue) is claimed to be owned by MGM in USA.
Argento seems to have managed to stop the already announced Italian DVD of Four Flies on Grey Velvet, and right now I doubt MYA was actually able to get it from Paramount for USA release (why would MYA succeed in what nobody else has?).
Anyways, these are all based on what was written at the lovelockandload forums, I personally know nothing. ;D
Oh well. It'll be interesting to see what happens.
