This has been mentioned before as well. I think it was something along the lines of "the PPC chip they chose was incompatible with any of the other Amiga PPC hardware or software". Useless. I could be wrong, though!
It uses the same core as Tabor so we'll wait and see how that performs although they did say they were considered using a different processor after receiving feedback from the community. There are much better choices available now too.
