This has come up before. No and it won't return.
1. It has its timeless place as a Black Ops map.
2. Treyarch have never recycled old maps.
3. The recycled MW maps brought little to MW2 except perhaps persuade us that new MW2 maps were inferior and needed support from better maps.
4. Any game dev relying on old material is not only potentially upsetting the former glory and becoming stale but also suggesting a lack of enterprise and creativity
Basically (and I personally don't like small ridiculously crazy spawn maps), if Nuketown is deemed an essential success there will be a brand new map nothing like it visually, but just like it in terms of attributes and entertainment value. We should expect that of Treyarch.
