I'm just saying that I'm working on what I think as the last update: 2.3, except maybe adding support for OS 6 which will make it 2.3.1, but that's later (once RIM releases the official TB 6)
The main features planned are as follows:
- Brand new active call and incoming call screens (because Fall Collection seems too "Flat" for me)
- Minor UI changes for homescreen
- Minor logo change (that is, Chihaya's kanji signature is removed)
- Minor UI change for dialogs (the dialog buttons are too big even for a giant's standard)
- Brand new lockscreen background (which makes me go fangasm everytime I see it)
Screenshots:
Homescreen banner - new Battery and Signal strength icon; new element arrangement
Lockscreen - brand new image
Active Call - Brand new image; new element arrangement

After this update, the work should be finished, and I'll finally make the Documentation PDF I've been longing for.
Also, after this version is finished, I'll begin studying about Android theming. My friend bought Samsung Galaxy Mini and he asked me to create a theme for him (specifically, Haruka version). The screen is 240x320, but the knowledge could be used for larger screens
The theme that comes to mind is THE iDOLM@STER 2 Allstars, the BlackBerry design is already in my mind, the Android will have to wait until I know the limitations of the device
If everything goes smoothly, you Android guys could get an unofficial THE iDOLM@STER theme around fall or early winter
