Nope, it is not available for 4.0.3 yet. Besides, you don't want it... Several people with CM and other JellyBean ROMs have had this for a while, it is TERRIBLE, unstable images, unreadable pop-ups, jerky motion, not to mention the removal of usable off-line maps.
6.14.4 is still considered the "golden" version, works perfectly. If you really want something new, try Waze, MapQuest, or any of the other various map softwares on the Play Store.
New Maps is now available in the Play Store... at least for me it is on my stock Rezound running the 4.5.605.14 ROM. Haven't tried it yet though... after the last couple fiascoes with Maps and the Rezound, I'm gonna wait a little bit.
