The NBA will be introducing some new city pride jerseys this season. Detroit has already shown their "Motor City" uniforms and the Lakers recently unveiled their "Hollywood Nights" uniforms.
This photo leaked awhile back. You can see Lakers' black jerseys. I'm assuming the Orange & Blue will be for the Knicks, green for Boston, etc.
There is a light blue and red jersey that could be for the Clippers. The colors are reminiscent to the Los Angeles Stars ABA uniforms that the Clippers wore in 2012. Click the pic to see the full image.

Aside from possible alternates, we'll of course have sleeved jerseys that will be worn sporadically throughout the season, which are likely to debut on Christmas Day.
