Was excited to finally see the PSR-E473 and PSR-EW425 finally announced; finally line out ports and even a mic input with gain/effects and especially interested in the 425 for the extra keys. It's almost like a portable DGX-670 (with unweighted keys). Still no availability in Canada and I spoke to a major retailer here and they still haven't heard anything regarding availability or pricing. Anyone have more info than I do?
