There will be one major version 11.1.1.8.0 (PS7) of WebCenter by end of 2013. In this release, following are some highlights I learned from Oracle:-
1. there is no more two solutions (Spaces & Portal) for WebCenter. Spaces will be the part of WebCenter Framework. Only one concept that is PORTAL.
2. We can create multiple portal from Web Interface.
3. You can import/export portal archive (PAR exactly like JAR/WAR/MAR) from/to Web to/from JDeveloper for complex customization.
4. All types of popup windows will be eliminated from portal.
5. You can drag and drop Web 2.0 components and taskflows on to the page from resource catalogue.
6. Migration among different environments is easy due to PAR.
