I love my MODO BASS, but I think it could become an UNBEATABLE product if you added:
1) Something like this newly launched Riffer: https://goo.gl/WwgwIv
It would be amazing!
2) A fretless bass
3) An upright bass
With 1) + 2) +3), this would be the only bass most of us would need. (As a non-bass player, I am particularly excited with 1). Since I own the AS Upright, I will be able to export MIDI riffs and play them with MODO, but adding something like it to MODO would be better.)
