Ugh, I certainly hope not. I hate Origin, the day EA selfishly moved from Steam was a bad day.
Its also what would keep a company like that from ever really supporting Linux as I see it. Its just so much easier to build your walled garden in Windows. Doing so in Linux takes at least some degree of support from the open source community. Which steam has been getting cause they have been reasonably cool to the community in return.
Origin on Linux... ya I'm going to have nightmares now. Sort of a careful what you wish for thing though I guess... imagine if all the PC game companies started support Linux and we had to deal with the same crap windows users deal with. (that is what it would take for that to happen though... we would have to put up with the Origins and Arks of the world)
