Well they appear to have continued with just the fifth ident since the 15th now.
For those wondering too, it also seems they have successfully managed to queue up the festive idents for longer this year
after they somewhat prematurely disappeared on the 24th last year.
BIB- which is, of course, the main problem with having an Advent calendar-themed ident, given the fact that Advent ends on Christmas Eve. A nice idea and well-executed, but not so good for an ident which is supposed to last up to New Year.
