Normally I'm the type who wants to know right now, but with my 6 days work week I want to have something to look forward to.
Regarding your second question. If u know the editor isn't going to be there, then I might tell him/her. But to be honest, waiting is half the fun. You do have a good point though, you don't know what else he/she is gunna win, so as tempting as it seems, perhaps this information should be kept to yourself. (just my 2 cents)
