I agree about the current title. The question is what title should be used. Most sites seem to keep the simple X2. I'll let someone else decide this one, but X2 probably would be my vote based on usage around the web.

X2 seems to be the most used; it would be the one I'd go with as well.

In any case, I've never seen that much alternate titles on IMDB (36!), wow

IMDb will always carry more alternative titles since they don't offer translations. Here, an alternative title should be deleted if it is added as a translated title. But still, many variations for this one.

I changed the title. If someone want a new discussion about that, just reply and we will go at it for another round. :)

Thanks all!
