Word on the smokepad has it that the mystical 'they' who control housing are trying to keep everyone from the same power school class housed near eachother. So if you don't know what class you will be in yet, then they probable also don't, and thus wont move you yet. Supposedly everyone gets a room move by the time they start P-school, and I have not seen any proof to the contrary yet, that said, I have only been here 6 months.
But yeah, ask your chief.
