No LAN port for IDC (Internet Direct Connection). Not a big deal - but it does come in handy with Music Finder suggestions.

I'm surprised that after a 3 year wait that they are adding only 5 Mega! voices and no SA2 voices from the T3. No additional DSP blocks ...

I would think that Yamaha would want to create a market for their expansion packs, but I'm definitely not buying more than one if I'm going to have to go through a menu process and restart my keyboard to change expansion packs. Imagine doing that during a performance!
