Funny, I was also wondering the same thing, not so much v3 final but when betas would start flowing, specifically betas with hidden line removal (sorry, I couldn't resist) :D
I've been starting to wonder what little Gibson is going to add into V5, and what I will be up to at that point! :o
I'll start a new thread:
Better human intelligence
GPS voice recognition enhancement for voice coordinate input in all commands
hologram display enhancement to include virtual drawer for scripts
enhanced datadump repository of Dad's mind for easier customer access
Etc...Etc....Etc!
