I don't see any rwd or awd accords coming to showrooms any time soon. Putting power to the rear doesn't fit with the family sedan image that has made the accord the breadwinner for the Honda family since the 80's. You're not suposed to do burnouts while you get the groceries
EDIT- I just realized you said TL and not Accord. RWD would definitely be nice for the TL but SH-AWD is way more likely since its already in use for the RL. Maybe the CL will come back to add awd or rwd. I miss the CL-S
