300 LC is coming in 2 years or so. LX will soldier on for 3/4 more years. They easily could have done more to the LC but you know they are saving the special stuff for the full redesign.
That would surprise me if the LX was to stay in production on the 200 platform while the LC went on to an all new 300 platform. I would think that would have to cause some major production issues building 2 different platforms on the same line. How would they manage that?
