It would be nice to a ColdFire cpu under the hood.
Perhaps...
However, I would advise everyone to wait until some impartial 3rd party has reviewed the ColdFire hardware. Elbox has been known to use misleading marketing before (Making big deal about Mediator pci<->pci speed which is mostly irrelevant, talking about megabits and not megabytes etc). I wouldn't be too surprised if the average performance of the ColdFire accelerator would be much worse than advertised.
Also showing the actual "Dragon" hardware running would certainly help proving it exists and works, considering the SharkPPC is still to be demoed running anything.
IMO you should stick with the real m68k for now.
