It's going to be awkward to do a comparative review alright (I don't envy you).
The notion that "omega is in continuous development" may well be true, though the less circumspect might uncharitably say "never finished".
A review has to be done as a "snapshot" at a given moment in time - what is true *then* is all that can be used in the review.
If (later) new features are added to either machine then that can be used as a follow-up to the review at a later date - if people are expected to buy a given machine *now* then the review can only realistically be made above features that are available *now* (otherwise such a review would be misleading).
Hopefully MD will see fit to provide a machine for review with all the latest FPGA updates in place so that a fair comparison can be made.
