It's worth noting that AEG's support of Thunderstone has, in the past, been very hit-or-miss. For quite a while it was unclear whether the game was even still supported until an expansion suddenly appeared in stores with no fanfare or promotion.
They also weren't great about keeping even the "current" stuff in print. The first Thunderstone Advance box became quite expensive even as they were actively releasing new Advance sets.
It's too early to assume the same thing will happen again with TSQ, but... just saying what their track record is like.
I have eared of that, but I think it is safe to say that AEG is now bigger, they have several game lines without this problem.
