Release older buildings for newer players!
Well, many of the items were limited time or tied to episodes, so it wouldn't make sense to release them again. They have released some old items here and there so you never know though.

Has anyone mentioned the "other" way that you can get old characters and buildings. I'm talking about going to the darkside. It's not fair to players who have worked hard and payed good money for these items but hey the option is there if you're willing to wait and do the digging on the inter webs.
