Channel 4 haven't had Christmas pres since the year before the previous idents launched, so there's really no way of knowing.
They had a Snowman & The Snowdog ident didn't they?
And they had pres, just not the idents other than that. A shame, but as much as the new regular idents haven't really worked it has been worth the change for their Christmas package. It is probably a good job we like it too as I suspect it'll be around until the next major revamp.
Shouldn't that have been posted in the "John Logie Baird has Invented Television"
