From the update (with much more on their website) :
Hey everyone! If you hadn't seen this already, the pre-orders for the new BattleTech cases and faction patches are available now. The bags and patches will be released in June of this year, and we are taking pre-orders for our first production run. Pre-order time is the best time to get in on ordering your bags as you don't have to worry about what colors are in stock, we just order what is requested, and stock from there.
