It may be an elaborate hoax, but My.IS member nyjinwoo has uncovered what looks to be a brochure for the 2009 Lexus IS 250/350. First thing, here's an overview of the exterior changes:

The front grille has been given the same extended chrome border and integrated turn signals that were included in last year's refreshed GS. The revised rear lights have also been changed, though the differences are subtle unless compared with the current design:

The most obvious change is the L-Shaped clear accents in the lower corners, though it also looks as though the rear lights are protruding somewhat. This was something I noticed when looking at the convertible spy shots seen some months back.

Interior shots were also included, and the only change I can see is the wood steering wheel:

If accurate, these changes certainly increase the edginess of the IS (I'm particularly impressed with the chunky rear light treatment), but will it be enough to carry the model through its final three years of production?
