For anyone interested (and local enough to get there before they run out) BevMax on East Main Street Stamford has these in stock.
I picked up a case yesterday (they come five in a case) while stocking up for the football home opener.
They had three full cases and one open case (on display) with three left. Highly recommend for fans of true German Oktoberfest beers. Reasonably priced as well as the cost (including the dimpled full liter mug) is similar to what the mug alone normally retails for.
On a side note (as we open the season in less than a week):
@karstenkibbe if you have any interest in attending the opener, or any other football game drop me a DM with your contact info. I normally have spare tickets and parking passes (hopefully after this season they will become more scarce). You can bring your kids if you want and you can tailgate with us along with joining us for the game.
