This news had me prestty bummed for a few hours, 'til the official response from Lego seemed to offer a little bit of hope again. I suppose I wouldn't be crushed if the SW line ended, but I do enjoy it and would prefer for it to continue on - especially that uber-cool mini line.
One thing I noticed with the third wave of minis, is that Lego appears to be shipping solid cases of OT product. I say this, 'cause at several different stores, I saw MANY Imperial Shuttles and Star Destroyers, and not a single one of the other two Prequel ships (until a month or two later). Very strange. I think they may have realized that OT sells way better than PT, and are adjusting their product, and case ratios accordingly, to protect themselves a little more...
It'll be interesting to see what, if any, further Prequel sets show up in the future. Almost all the recent and upcoming product is OT, which is perfectly fine by me!

Just glad to see they'll be sticking around. Now bring on some more large playsets, get rid of the "Lego Shop at Home" exclusives, stop rehashing vehicles (including the last 3), and we'll be back in business!
