Yea, it seems odd not to wait. There are lots of students that feel cheated by online classes, and understandably so as it's not what they signed up for. To start with an early announcement that classes are going to be online, at least initially, does seem like a recipe for an enrollment disaster. Though to be fair, I'd be pissed as a student if, after I paid my deposit and made plans, a school made that announcement. There's something to be said for being honest about what's likely to happen, even if it costs you. And as you said, the faculty will need time to prepare for online courses.
I recently retired from a faculty position at a midwestern research university, and I'm really glad I missed the sudden switch to online instruction. I taught using extensive small group discussions in classes of 120+ students, and it would have been a cluster **** to try to move that online with little time to figure out how to do it decently.
The pandemic has already cost universities millions of dollars. As they consider the possibility of remote classes into the fall, they’re worried about losing students, too.
