It's been listed on Amazon, and according to Shawne Kleckner it seems to be real. Personally, I'll wait till it's listed on Rightstuf before pre-ordering it.
Even if the 1st season was animated in SD, I look forward to any sort of upgrade. It'll be a good excuse to rewatch the first season again, too! I hope S2 comes out on BD as well, simultaneous release or not.
