There's a lot of people out there waiting to hear back from their POs about full proposals. Between email, the blog and twitter I have gotten a lot of people asking about notifications. Here's what I know so far:
I have been notified on my DEB proposal that it is in the gray zone of "fundable pending funds". I heard back a couple of weeks ago. This week a colleague of mine got a phone call about her IOS proposal. So... notifications are starting to go out but are very cluster-specific on timing. If you haven't heard back yet it is not time to panic.
Remember also, that the preproposal deadline has been pushed back to around the 20th of January, depending on your program. Be patient, you have a little extra time in January to polish up that already successful preproposal. Above all, don't ping your PO about the decision. It's not like they just haven't gotten around to letting you know, if they could they would have already done so. Be a little more patient and be happy you'll only need to tweak your preproposal if your news is not what you hope.
