Yes the next update will feature bots. Do note that I stopped coding them a couple months ago to focus on gameplay enhancements. As it stands now they are a great training tool, but not sufficient enough for solid human replacement. They hold up REALLY well in online play, you can't tell if they are a bot or a human in terms of latency and the like (unlike L4D...)
Once the gameplay enhancements are done I'll go back to bots to bring them to a playable state for at least deathmatch gameplay. I don't think we'll see them playing LALD competently in v4.2, but that can easily be addressed with a post-v4.2 server update to the python scripts!
