Does currently not supported mean it will someday be supported? Dr. Wolfram's initial blog post stated:
"The command-line Wolfram Language is quite zippy on the Raspberry Pi. The full notebook interface to Mathematicarequiring as it does the whole X Window stackcan be a trifle sluggish by modern standards (and we had to switch a few things off by default, like our new Predictive Interface, because they just slowed things down too much). But its still spectacular: the first time Mathematica has been able to run at all on anything like a $25 computer. (Note from me: the Mathematica benchmark on the RPI 3 is > 50 times slower than a modern laptop)
And its the whole system. Nothing is left out. All 5000+ Wolfram Language functions. All capabilities of Mathematica and its notebook interface."
With the picam, the Vision/Image system would be fabulous for robotics and I hope it gets going
