My assessment:

Gimmicks:

- Popout explorer windows (So you can get the old style Pending Changes window, if you like)

- Make comments and discussions on code through web UI

- New release management plugin

- “Team rooms” allow your team to collaborate on code

"I'm OK with this" improvements:

- “Indicators” in code that give you info about blocks of code

- Cloud load testing

- More agile portfolio management options

- Test cases can be worked on through web UI

Real Improvements:
