The book is correct about where Modula-3 was developed. The people who developed
Modula-3 were, as you might expect, familiar with Modula-2 in the form that it
had at that time. When they started working on the design of Modula-3, they did
have contact with Niklaus Wirth. It was in order to discuss the design of the
language, though, not because they were worried about the name. The name 
Modula-xx is not a registered trademark (unlike PL/1 up to PL/100). I wasn't
involved in the development of Modula-3, so I can't say for sure, but I doubt
that Wirth had anything agains using the name Modula-3.

Aside from the ACM journals, I use the Usenet comp.* conferences to try to keep
up with what is happening in the world of programming languages. It isn't easy!
