Got same email and also got a feeling everyone who is in the system but hasn't received a rejection to date has now been updated to status "hold". Being the pessimist that I have (unwillingly) become in recent years, I think this is just a friendly way of them saying "we've been through enough applications now, we'll continue the chopping exercise in 2013".
Unless that is someone can tell me that many more rejections have gone out since the beginning of this week?
