I'm wondering if we will be able to make online lobbies like in GT5/GT6, I dont know if it has been confirmed yet.
I hope so since I think its by far the best part of GT6 and the playing mode I use all the time with my online friends.
In the menu of the beta there is an option that is just called "Online" apart from the "Sport" option.
We can only assume that would be where we can make our own open or closed lobbies like in GT5 and GT6
