Cons Maybe this could work but I have never checked:
- Local customers tend to preferr local domains
- The SERPS are not the same all over the world. If somebody is searching from Germany, German sites are preferred (at least from Google).
- Google likes larger sites so spreading your content to different sites could be a disadvantage.
- Content is on www.domain.com/de ...
- www.domain.de is hosted in Germany but has as 301-redirect on www.domain.com/de
