The a400 came out when it was said it would be out, when DUNE announced the pro running the 8910 over a year ago, sigma said sdk would not be finished till end of q3 2012 hence we all knew the pro would never see the light of day, a400 followed the schedule it has had all along. Now did they push it out before xmas to drum up sales, I would say yes but what company would not if they could, Also who knows how long the exclusive period they have on the 8910 chipset is, if its only till year end you need a product out to take advantage of that deal.
