I've been wondering the same thing, but using the "first month" as a benchmark. Was thinking roughly about 50k in the first month. Have no clue how the first 24 hours will go though.
Keep in mind, online doesn't start until the 1st of April. So, I'm assuming you mean 24hrs of online orders being accepted.
