Well, I'm the one who suggested this, and it's just a theory, but... the new SD is nearly identical to the first SD playset, and retails for 30% more. Ditto for the new AT-AT, and we've jumped 10% on that. The new B-Wing has a similar piece count to the first (non-UCS) B-Wing, and retails for almost 50% more, the point being that Lego likes to raise prices. However, they don't raise prices on existing sets (with the exception of AS). I do know that 10188, at the same MSRP as 10221, weighs several pounds more. It also has a better price/weight ratio (generally more useful than price/piece; otherwise sets with lots of small pieces appear to offer awesome values) than any exclusive set released in the last half decade or so except for the modular buildings. I'm willing to bet a Chima Speedorz Starter Set (someone please take me up on this; I have way too many) that the Classic Collection has a worse price/weight ratio than 10188. Winner pays shipping, of course, and reserves the right to cancel the bet altogether. Honestly, what are these things good for? They bore children and move too fast to make useful cat toys...
