As long as its under 30 pounds its workable, but as Paul DeBra mentioned, using modern technology and techniques, things in theory could be made lighter. Some concessions could be made like no internal speakers and a lighter case. I am very curious to see how they deal with all those challenges. That said, the video mentions a weight if 11 kilos, a full kilo lighter than the FR-8X.
Possibly a misunderstanding on my part, and it will have no acoustic accordion side? That would be a bit if a letdown, but hints point to that, and after looking at the video several more times, that is exactly what I am seeing.
Natural air flow system combined with dynamic bellows behavior technology, which accurately simulate the bellows response of an acoustic accordion
So if you are simulating an acoustic accordion, they are replacing it with digital tech, as I see that phrase. All it means is that instead of actuators under the buttons, the mechanisms of an accordion are used and the actuators are placed where the flap covering the hole to the reed normally are. This may give them a feel closer to a traditional accordion at the risk of additional hardware that could potentially go bad after prolonged use.
Anyway, its certainly going to be interesting to see how that is handled.
Edit: Seems Cory Pesaturo is involved... good for him, I liked him ever since I saw his TED talk on YouTube, he will make a super representative for this new accordion.
