I was wondering in their news post the 31st of March they stated the following:
* Proving grounds has begun to arrive in Canada, Australia, and New Zealand with more arriving in the EU in April, and then the USA in May.
* We've continued to release Origins boosters as waves of printings complete. The next batch will arrive following Unleashed's launch in stores with an even larger shipment arriving later in May.
I Have actively been looking at different stores in Germany, the Netherlands and Belgium to find the reprints of proving grounds and to look for these release of Origins boosters, however I have seen nothing. Currently we are almost through April so I was wondering if I have missed an update, or if other countries in EU did get the restock.
