Whoever said the RSX replacement is a shortened TSX is probably closer to the truth than the poster thinks.
Imagine a two-door coupé version of the TSX (akin to the coupé version of the current Accord), but powered by the same rumored engine used on the 7th-generation Honda Civic Type-R hatchback sold in Europe and Japan. With 240 bhp (SAE) on a shortened TSX body, it will essentially be a revival of the old CL coupé but much more fun to drive.
