I did my 90 day report this morning.  The IO didn't even glance at the paperwork.  He just scanned my passport, printed a new reporting form and cut it in half with a ruler as a straight edge, stapled it in my passport and that was that.  5 minutes after entering the office I was done.  

I asked him about the move to the new office and he said "Maybe January".   But he obviously didn't know.

In Hua Hin they don't require any paperwork for 90 day report renewals at all, you just take your passport, they scan it then print the paper and put it in the passport.

It's been like this at Bluport in Hua Hin for a few years now. They do always ask if anything changed, so I get the impression they would want the paperwork if something has changed.
