Is it just me, or is he spreading himself awfully thin these days? I mean, I don't know him personally so it's entirely possible this is all within his capability, but "Loop transport", "LEO Spaceship", Tesla and now Mars too?

LEO spaceship and Mars are on the same development track (humans as interplanetary species / retirement on Mars is the final destination, rockets and LEO spaceship are first steps on the track). Also it's nice how he managed to make his three companies support each other by flowing tech and cash between them (e.g. Tesla using SolarCity tech for charging).

In my view the first version of the Loop (which seems to be something like electromagnetically driven 3-4 winged needle (something like StarWars X-wing starfighter without engines) in a pipe - you need to go supersonic to outrun your sound (for comfort), this is your Concord, and shock wave from the needle will be hitting the wall right in front of where the "wing" ends would be touching the wall, so one can have correctly designed wingtips doing "shock-waveriding" near the wall, instead of touching it, this is your "airhockey") is for ground transport while it will allow to develop/refine/test the next version of the Loop which will be used as the first stage accelerator for space launches
