Ground Zero Games have posted an update on the status of orders from their site.
From their website:
Well, things are still behind, but there is at last some light at the end of the tunnel (and no, this time it’s not some ****** with a torch, bringing more work!). I still have a large number of orders to process and send out, but having been working practically non-stop on them over Christmas and into January, the pile is finally starting to go down a little. Most of the orders placed during the Christmas offer period have now shipped out, and the remaining few of them should be done by the end of this coming weekend. Please be aware that if you placed an order after the offer ended, these are almost all still in the queue to be processed and will be done in the next couple of weeks, all being well.
Check out their site for full details.
