But if they say a release date and then fail to release it then then your hopes will be dashed anyway. Release dates don't help much 
If the release is so imminent that they are "gearing up" for it they must have an idea of when they can release even the beta. If they are worried about over-run of the date, add a month or two. Doing that will allow some breathing space. I do that sort of estimation ALL the time at work, when asked for a deadline of when I'll be complete, I guess at when I can be finished if I can work at it steadily, then I factor in all the interruptions... add a week or two for contingency and BAM out pops a due date.
For all those lost on the "Thursday" thing, it's a running joke. Whenever the devs were asked in the past, all they said was "Thursday", no commitment of year, month, or week. In other words, Thursday never comes, it's like saying "I'll post my resignation tomorrow", or "The check is in the mail"
