Sadly, we will not to our satisfaction.
James does a good job in communication, that is what i am sure of.
It must be another case of not beeing able to tell more because it is not decided yet. I can not repeat often enough, jolla changed focus and this device is not ment to be a gamechanger in public recocnition but another small stepstone to not let the community break away more and have a decent demo device to catch corporate fish.

So him giving exactly the sentence we got, means not more and not less than stated.
Full Support for one year, mainly to pay 3rd party licenses.
Given intex put out a whole device for 69$ including those licenses, 50€ hopefully has some overhead to pay for past or future jolla developement on removing beta state of sailfishx.
Those licenses could also be the reason if the continuation program will cost additional money to continue to use Alien Dalvik and M$ stuff after 12 month.

This all smells like jolla will introduce some kind of paid feature to the store to manage subscriptions or sell single 3rd party features, doesn't it?
