Last I heard they already had this up and running on dev builds during beta-phase but the problem was how to fit it into the limited memory of the ps3-version. I'm pretty sure it will eventually come to at least pc some time in the future. People having trouble with limited crossbar space, have you activated different sets for weapon sheathed/unsheathed? I only have to tap R1/RB once to jump between my two crossbar-sets that i use while fighting which I think is pretty hassle-free. Gives access to 32 skills with the click of a button and the crossbar is not cluttered with mount-commands or teleport etc. while fighting
