And it it more logical to do so because the problems that many (including me) have with GT sport is not in driving gameplay but the lack of classic GT traits and features that normally we expect to have in a main line GT. If playing more like GT sport means that we'll get the game sooner raher than later then I, personally, do not mind at all.
About the trailer, I loved but it felt like a drop in the ocean althought it is normal because it is just a reveal trailer so many changes will probably come for the final build of the game.
GT Auto and Tuning parts are back so I'm very happy, I'm quite curious to see what modifications are available in GT auto. Hopefully a expanded version of GT6 GT auto.
