release a model above the PSR E413 at Summer NAMM?

this is very close to being a decent board. it has an arpeggio function and two "sound editing" knobs, a basic sequencer, solid sound set....but it's troublesome to import styles (no thumb drive, usb to computer instead).

seems like with just a few upgrades from existing psr line and the addition of full MIDI (I'm not sure but I don't think it has midi in/out), this would be a winner.

anyone heard anything relating to the lower Yamaha arrangers?
