I don't know much about US, less Europe. Generally the popular shows like best three friends: naruto, bleach & one piece I guess! maybe but I do observe more people who like anime based on visual novels, like haruhi, I think that one has persevered all this years not a big fan of it but I noticed that.
Pokemon... as long children exits so shall be Pokemon (long live to pokemon!!) xD I've never be into pokemon, not my thing, not because i'm not a kid, because is boring to me, (I still watch cartoons) but indeed is a generation of series, that [right now] I don't feel is too popular right know.
If I would say something about centre-and south america, there naruto, bleach (losing popularity, may be due to its completion.), one piece, fairy tail, katekyo hitman, saint seiya after many years still a furor, evangelion, D gray man, even death note I think around the world many titles, old or new still cause impact and forever-ever titles like i don't know.. pokemon, evangelion, saint seiya (as long the industry keep working on them or not) popularity still resides.
