Just like the tank battles of WWII, the Girls und Panzer v1 BD campaign will be analysed by marketing strategists in the future and become a case study. You have the initial blitzkrieg, then the lull to regroup as they ran out of supplies and the second offensive in the 6th week :D
Seriously though, looking at Actas and the things they've done I'm not surprised that they grossly underestimated the production of the BDs. If their official website is accurate, they haven't produced an anime as the lead studio since 2007. Not only is this their biggest hit ever, I think the sales probably outnumber the total sales of everything else they've produced.
And if they ever want to make a Girls und Battleship anime, Actas actually has some experience with Tactical Roar back in 2006
