My guess to answer some of the above will be likely 2-3 daytime, 2-3 night time events to start off. This is how it started in the earlier years in Mexico and it grew to more like 4 day and 4-5 nights. Regarding the Sonar question, the answer is yes, it was very much a festival and then "OFF BPM" events. However, I'm not so sure that will happen in their first run in Portugal but that is just my guess. As for the lineup, I would check past lineups for say 2015-2017, I would think they'll have their usual suspects (definitely Apollonia, Vatos Locos, Guy Gerber, HS82, likely to see Solomun). I'm curious to see how it works out but I wouldn't attend myself. BPM was great in past years but have always been very disorganized, I'd hate to travel that far for a mess on their first run but it is of course a lot closer and easier travel wise for most here.
