Proper Placement of the TLX section

Is it really right to place the TLX under the TL subforum as a 5th gen TL? Isn't the TLX as much of a TSX replacement as it is the TL replacement?
Price wise it starts at approx the same price as a brand new TSX for the 4 cylinder model(~$30k), and approx the same price as a brand new TL for the 6 cylinder model.
As much as I would love to say the TLX is an "evolution" of the TL, I don't know if I can lie to myself.
I personally feel the TLX shouldn't be under either the TSX nor the TL subforum, but be under a new subforum by itself.

Is there something I'm missing? I'm open to debates for and against this issue.
