I'm pretty addicted to DOTA(W3 Custom Scenario) for a while now(playing/watching).
It should be pretty popular at Germany too. There are lots of great players and teams from Germany. I'm not sure about WCG but KODE5 has announced DotA as one of their main games for their 2008-2009 season. Although current stable version sucks a little (too much farming, less action) im still hopeful about new improvements.
