It's not impossible, but it would be uncharacteristically early - the BBFC levies a charge to certify an item, so publishers tend not to do the clearances until the release is in its final stages of preparation so that if something goes wrong (eg an artist refusing permission, or music rights going awry) they haven't wasted time and money having something certified that then has to be either dropped or edited (the latter requiring resubmission and a second fee).
I guess if there is something coming we'll hear about it - and of course the main feature will turn up at the BBFC in due course.
The BBFC's work-list isn't a guarantee of a release, of course, but it can be a useful guide to what's in the pipeline
