I was poking around on B&H's site and noticed the the 600 is 'discontinued'. Also noticed that BestBuy doesn't have it available online for ordering anymore. This made me think - a couple of years ago when the 800 was discontinued, BestBuy clearanced them for $100. Will they do the same or better for the 600? If so, I hope I catch them in time as I missed the 800's. They were all gone by the time I got there.
