While I agree with your overall reasoning and do think the RSX will be discontinued (at least in it's current form), I have to say I'll be very disappointed to see it go. As a previous Integra owner and a current RSX owner, I'm obviously a little biased. I love the lux/price/performance ratio. There's really not another car that comprises those same attributes.

I was thinking the RSX replacement might end up being something a little more like a 2-door TSX, probably with AWD at least as an up-market trim level.

Edit -- dammit, Ochdx beat me to the 2-door TSX comment.
