Whilst this sounds good in theory, it's somewhat hard to demonstrate to the 'general mass' what is going on with the emulator.
For instance, would most people understand the significance of MFIFO fixes, or VU0, VIF, SIF, GIF, DMA etc
Most people won't care for information unless they can see the 'graphical result'. EG:
Final Fantasy X now showing Terrain polygons (VU / VIF fixes).
The devs work in a rather fluid / erratic manner as there is no simple stage by stage process of working on an emulator, and various things are being worked on at anyone time, that interconnect, also the betatesters / devs have enough on their 'todo' list without having to update some thread continuously.
If you wish to keep a 'relative' track on PCSX2 activity, the CVS 'changelog.txt' will be enough.
As for the status of the 64bit version, it's currently very experimental, though showing early promising signs.
