There does seem to be a mix. All of my cards are embossed, but one German Maestro card I’ve seen is not. I also remember one non-embossed card a colleague received from a UK bank, but I can’t remember which.

“Electron” cards, which may not be used at all with manual imprint machines, have never been embossed.

It's not clear how widespread this is, as yet; I recently received new C+P cards, from two different UK banks, which are embossed like their predecessors were. Perhaps it'll be a different story when they next expire. Not all merchants have converted, either; one of my cards was "zip-zapped" by a taxi driver in Brussels earlier this year.
