I’m definitely In!!
I am already ready for this next Ludum Dare and I can’t wait to get started. Hopefully I can get a working game done this time. 
Tools will be:
OS: Windows 7 Professional x64
Platform: Web
Programming: Javascript with Eclipse Luna IDE
Engine: Phaser JS
Audio: Bfxr
Hosting: http://tjxx.itch.io
Fuel: Lots of Coffee
White wine – Chardonnay or Pinot Grigio (not sure which, yet!)
Good luck to everyone!!
Edit: I made up my mind to use the Unity engine in 2D mode which is installed on my Windows machine.
Edit 2: Changed programming language to Javascript, sound engine to Bfxr, and the possibility of using Unity in 3D mode.
Edit 3: Late switch to using the Phaser JS engine in the latest Eclipse IDE instead. Unity is still too much new to me.
