Swore we had a thread on this but I must be thinking of the season two announcement thread (maybe it was mentioned there...). Makes sense to release a BD box of a successful, otaku-targeted, previously DVD-only series before putting out a second season though!
The actual image with proof is farther down: link
Arrgh, I am very likely going to have to buy this. I've been trying to cut back a bit on what level of show I'll buy a BD Box for, opting just for 10/10 shows and some top level 9/10s, but I think Saki might need to be one of the latter. I actually might not have decided to buy it if the second season were announced, but knowing more is indeed coming makes it worth it. Since it's almost guaranteed I'll be importing the second season.
