I'd imagine if they want to maintain the same functionality of cartextures from NL1.x, NL2 cartextures would probably let you change the new bumpmaps, normal maps, specular, etc. Or they might introduce an interface that lets you change the hood logo and various parts, but such an interface will probably be a lot more limited in options. NL's updated steel coaster trains already limited a few options, such as the texture on the wheels.
In any case, modeling with NL2 should be interesting as it'll support many more features such as those normal maps.
