Exactly. Lego is creating a supply vs. demand problem that may ultimately devalue their own product and reduce/wear out interest. There are too many awesome sets being churned out that it's hard for collectors to keep up. I find myself in this boat. When I first started collecting as an adult I had missed things like the Black Pearl, QAR, UCS R2D2 v1, UCS MF, great CMFs, etc. So I started purchasing these things on the secondary market and started grabbing new sets as they came out. Now that my collection has grown so much, not only is space an issue, but so is keeping up with all the sets I want just in terms of new production from Lego. I've got a massive backlog of sets to build and notice that I'm being much more selective in my purchases. I've completely stopped purchasing retired sets as well. Plus with all the sets and variations I feel it's becoming more challenging for collectors to even know what sets are retired and they are missing once you get too far down the road.
Lego needs to keep their product relevant, collectible and valuable. Producing such a large number and variety of sets these days seems like massive short term growth as they capitalize on interest, but long term decline due to burnout. The market is just getting flooded from all directions. People will grow weary and move on to something else. Where's that bubble thread... lol.
