Hard to tell if they will actually push for this variant. Toyota had released that they were planning on releasing 6 new hybrids by 2012, 2 of which would be Lexus and that included the CT.
Now that there are already a Prius V and Rav4 EV variants coming out they had already speculated that the 4 Toyota Hybrids would be Rav4, Sienna, Yaris and Corolla. This leaves one Lexus, which I can see going into either the IS or ES. Another tell tale is that Lexus from my knowledge has not filed for a CX trademark. It filed for CT200, CT300, CT400 two years prior to its release. Only time will tell
