I reckon VGC is high on almost everything for hardware. The US economy is slowing down, all the consoles are very old - the 3DS / Vita are tiny yet, and with a 40 / 35 / 21 split between Wii / X360 / PS3 in the US having one big game a month just isn't going to push big hardware numbers anymore. There is a chance Microsoft's numbers will be up I suppose because NPD will have found a way to include that "$100 downpayment plus future $20 payments" thing into the numbers at Microsoft's stores (I've never seen one though?), but that proposition is still pretty expensive long term for a seven year old console.
