So to answer my own question, it does not appear XBox owners get access to the 1966 West outfit...which is really kind of messed up that we get the car, Robin, and Catwoman...but no Adam West Batman. I can't seem to find any official answer from WB, but it'll be an annoyance if we never get them. 2/3rds of a themed costume DLC one but not the main character....bleh. I think it was also a pre-order bonus (not sure?) for the PS4, so some PS4 players may still have the 1966 DLC without the West costume. Kind of a poor choice for exclusive when you had other DLC planned around that theme.
For what generated more discussion than it was worth, I looked at both the XBox and PS4 before I picked one (and quite a lot at the thread here where people were debating them). The list of exclusives I wanted was about three times the size for the XBox vs for the PS4. My brother and I use the family sharing which is awesome since we take turn buying games we can both play, so that was a big plus as well. And most of my co-workers are also on the XBox. I don't regret my choice for a minute
I would eventually like to own a PS4, but not until there's a few more exclusives which aren't just remakes of titles I already own for the PS3.
