Well... I just played push game mode with bots in local play and it was really entertaining 
The new admin menu allows you to change map to any game mode, so I tried changing map to a push version. And it worked. And it spawned bots on both teams, hell yeah!! 12v12 with bots is possible with the new admin menu. I don't know if it's intentional, but I'm so glad I found out about it! Please don't remove it 
So playing any game mode with bots is possible already.
I must say that the bots in Sandstorm show a lot of promise! Even while there are some bugs (weird illogical behaviour or getting stuck sometimes) and sure, a lot of improvements can be made to certain bot features, the bots already do some things very well (like use the MG truck in push!). Sandstorm bots are way ahead of the old INS2 bots already. Good job AI guy at NWI! 
I am going to fool around with local play a lot now and I will be gathering some AI bot feedback at the same time, that I will post later in a bigger separate post.
Now I'm able to enjoy the game again while having my morning coffee!
