Drops tomorrow.
The car list is pretty small by today's standards, (4 Hondas, 5 Mazdas, 9 Nissans, 4 Subarus + Unlicensed AE86, 3000GT/GTO, & Lancer Evo), but they claim many more are coming through DLC (which could be for better or worse, monetary wise).
Looks like they at least went to great lengths to model a lot of modifications & the map, tmu, is decently sized.
