And none of the sites I've been to show national vote totals in terms of number of votes, just percent (though I believe you that the latest numbers, such as the ones from Yahoo.de are from actual counts, not exit polls). Nor do these sites indicate how many votes have been counted and how many are left to count.

This is really, I think, a question of the culture of election reporting, which varies widely from country to country.

I've noticed that in UK election coverage, for example, there is enormous emphasis placed on "swing" (percentage change from one party to another...reported in these German elections, but less prominently; and even less prominently reported, at least on election night, in the U.S.), as well as what the British somewhat misleading call "majority" (which we in the U.S. would call margin of victory) in each constituency.
