My humble prediction,
Sales will rise as soon as the first deliveries are confirmed.
It is obviuos e.g. Jolla is holding themself back with promotion or even proper mention to prevent another waterloo for themselves.

This tablet will sell because of its history if available and does not sell because of its history as long as it is in the making.

I promissed to do some promotion by collecting ideas here and i have some write up already but honestly, without a finished product, all effort would be tainted by historic events and the little cannon fodder i have would be a flash on the straw if not backed by events/release.
