That must have been interesting for the designers and test team, to make sure that the Push platform is prepared for some unknown upgrade eight years or so from now. We can imagine what that might be like applying a Moore’s law kind of prediction. I imagine they tested some options already and have some specs set for their first upgrade.
Ableton no doubt spent a lot of time consulting with Intel to get the interface perfect.
Even battery technology will work to everyones advantage. If i was buying right now i probable would choose to live with the controller for the time being, and be ready to get an upgrade later.
And Intel might even add cores along the way, years out.
