I wouldn't get too exited. Honda almost has an obsession with staying in the middle of the road and focusing on making the best possible car for the middle of the road consumer. They do sometimes branch out in other directions, but never for very long. They had penty of chances to play the performance game and maybe the new NSX was a belated attempt to catch up, but with that being cancelled it's pretty clear they're not serious about joining the AMG-M-F-RS club. Even if they did an RWD RL, I can't imagine Honda giving it an engine with serious cajones. Most likely it would just be intended to be a better 5-series competitor.
