How should the year '2008' be pronounced?
Well, almost everyone says 'two thousand and eight', yet twice within the last week I've heard it pronounced as 'twenty o eight' on TV - by speakers for whom English isn't their mother tongue; possibly influenced by the convention in their own languages.
In a couple of years' time I should think the conventional usage in English will revert to what it was previously though and we'll start saying 'twenty ten.'
I've always thought that the reason that we say 'two thousand and eight' is because of the film '2001' which was pronounced as 'two thousand and one' to make it sound more futuristic.
