I had hoped for a Montage which would allow for the use of larger sound libraries by means of ssd streaming technology, just like the Kronos - thereby narrowing the quality gap between hardware and software instruments. Additionally, I would definitely have expected that all features of the MoXF/Motif XF would have been at least maintained if not improved.
But
-the full functional sequencer has been reduced to a simplified recorder
-the maximum free flash has been reduced from 4 GB (using Mutec flash boards) to 1.75 GB, so that large libraries cannot be used.
In addition, I think 50% of the instrument are wasted in my case, as I'm absolutely not interested in the FM-X engine (unless Bert's demos manage to turn me into an electronic sound freak).

I still have to check all sound demos in detail, if the ROM sounds are spectacular, a future lightweight version (MoXF successor) might be interesting for me.
However, an updated Korg Krome with Kronos features and an acceptable keybed is perhaps earlier to be expected...
