Huh? Where did I write that they should stop working on AI?
Maybe I should make even clearer what I meant: in every project there is someone (who is normally in charge) who has a "vision" of the direction the project should take. That person then bullies (e.g. by singing very badly and very loud) the programmers and artists around until their work fits his/her "vision".
Now what I am saying is: we will see whether the "vision" for AI is any good by the way the "vision" is imposed on SL. If I see actual playerfriendly changes in SL (e.g. the reduction of wasted inventory space for garden/sanc-keys from 11(?) to 1) I will be convinced that the guy in charge of AO (Marius - right?) will make AI a good expansion.
Everything else, like screenshots, dev-chats etc is just marketing and thus meaningless. I based my decision to preorder SL on Dev-Chats - I will not fall for the same trick again.
Whether AI will be any good we will not see by "appetizer"-info on a website but by the changes INGAME.
