I don't think that without offline support for the bots the game will actually be playable at launch.
No company sizes their servers for peak user numbers, and the hype for the game is huge.
Without offline support I strongly believe a lot of people that purchase the game will be locked out and completely unable to play the game for days to weeks (depending on how long the initial wave of players lasts).
I can't recall the last time the launch of an "always online" title went smoothly.
I for one will not be purchasing it until offline support for the bots is confirmed. I was actually thinking of pre-ordering, the only thing holding me back was that I lacked confirmation of offline support. Good thing I waited, I don't like refunding games.
