I don't think Vimm answers these, he just releases posts when he does get a new vault. Right now I believe he's busy with the Saturn and (possibly) the PSP vaults, so I feel like we're not gonna get a new big vault anytime soon.

I have been wondering for the past couple of weeks if there would be more consoles added, if so which ones. I know how much time and effort it takes but I'm curious.
Keep up the great work!!
