The Demise of Transylvania and Culture?

Someone asked me yesterday that since there are now more Romanians in Transylvania is this the demise of Transylvania's Culture?

Okay Two things:

1) in Transylvania there was always a large population of Romanians, in many parts they were the majority of the city or town.

2) Define The culture... which one? what era?

If we're referring to say the German population, I suppose then yes there is a demise of the German culture in Transylvania, but I would disagree for the Romanian Hungarian cultures due to their larger population bases in Transylvania.

What are your feelings?
