I don't think they do announce who the public had voted for over the series - but digital spy certainly seem to have some insider info, although I can't vouch for the veracity of the comments about the voting!
I'm not convinced about it being entirely down to public voting as you can't make people vote on dancing skills rather than the fact that they happen to take their shirt off a lot etc. Don't like the lack of dance-off this year either, but that's because it makes the results show a non-event more than anything else.
