Well it is standard practice to clear out the old line, I'd imagine that HK released last years line around the same time. Weather or not it was on the same day or not ... *shrug* .. I doubt it .. but around the same time period
I was at Fry's today-last year's HK's are on sale. The 525 was $499!! Unfortunately, they were sold out except the rather dinged up display model They're gone at outpost, so the supply may be drying up. Good luck.
