There are only a few informations about the next version of SP, called SP 15. But I can imagine that there will be more informations in the next weeks. But I dont think that they havnt changed any well-known features. Maybe there will be some changes but the most common behaviour will stay the same.
Something I have heard is that they have:
- Changes to the Object Model
- Switched to pure HTML5
- Switche to .NET 4.0
But this infrormations are from other threads, so I am not sure about this changes.
