Even though the low-quality image doesn't help much to track all the changes -or for that matter, to make out if it's the coupe model with a new grille or the sedan, but it looks like the 2010MY Altima gets a newly designed front bumper and quite possibly, revised headlamps.
Nissan previously informed us that the all-three variants of the Altima aka the sedan, coupe and hybrid models will receive "refinements to the exterior, interior and option packages" for the 2010 model year with official details to be provided closer to the car's on-sale date in fall 2009.
We'll keep an eye on the story and keep you posted if anything new turns up.
