All wikis will sooner or later be transferred, there's no way to stay on the legacy platform for forever.

Blogs will probably exist on UCP but I don't think it's been confirmed.

Staff are trying to get competing wikis to merge with each other but I don't think any wikis are being shut down unless a merge happens.

Comments will exist on UCP, the status of chat is very much up in the air as far as I know
