If it is really true that they will make a "new batch", I assume that Oskar's ball mechanism mass-produced could make the difference.
The ball is available at Shapeways for $20.67 since many months.
As far as I remember, only Burgo and I have made reviews about it, very positive reviews.
I cannot imagine, that anything else can be expected:

This puzzle has undergone five different prototyping’s and debugging. It has had two complete sets of moulds made for it. It has been in the production process for over seven months now.
I have three Mosaic Cubes and none is really bad, but the one with the ball is clearly the best.

As of today, it is available from Meffert's!!!
