This is absolute speculation so take it for what it's worth, but I get the feeling the class may be overfull again this year, just as it was two years ago. My reasoning is two part: 1) They extended the deadline by which accepted students could request a year deferal from May 1 to June 1. 2) I applied for a deferal and was told it would be granted before the committee even had the chance to review it.
Seems to me they want people to defer, which suggests that they may have too many students again.
Again, total speculation on my part, but I thought I'd offer my input.
