Is ICS truly dead?

Does having one wonder-making city work? I thought I read that you could only have two world wonders and two national wonders in a given city.

Actually I think that may be two non-obsolete world wonders in a given city, as I believe in my only game to date I was able to build additional wonders in Rome after some of them obsoleted. Or maybe I just imagined that.

I think you can have unlimited world wonders (both active and obsolee) in a city, but only 2 national wonders.
