Dude, KIAH was released today. Don't you think you should give it some time?
First, I'm sure the FSDT is going to take some time off, since they just released a new airport.
Second, They are probably going to be re-doing some older airports to get them up to today's standard.
Third, KSEA shouldn't ever be done due to quite obvious reasons, as stated in the past. (FPS, VAS)
