Though I'm hardly a networking expert I did some contract work implementing NDN simulations so I probably know a bit more about it than most people.

I'm highly skeptical that data entities provide a better (or even adequate) base abstraction for networking than network addresses associated with physical machines (ie. hosts, routers, etc.).

It seems to me that the problems NDN wants to solve, primarily content caching, would be better addressed at a higher abstraction level, as I think CDN's already do. This is my opinion, and I'm certainly open to being proved wrong by more qualified viewpoints.

As for the likelihood of NDN ever (a word I would almost never use, especially in regards to technology) replacing TCP/IP, it seems hard to believe given the extreme slowness with which IPv6, a comparatively minor change, is being adopted.
