And what would be these issues?
Physics wise is almost perfect, for many better than the competitors.
Sounds are great in many cars.
Graphic is ok for me and is going to be improved.
We got rain, night, live weather incoming if I understood well.
The new UI seems will be great.
In the future we'll have more cars and tracks and Marcel said that they plan to update to the new tech all the old content that they can get licensed.
They are introducing a new system for the multiplayer.
The current cars and tracks available are great (but not enough content according to some people and that's true).
The mods are increasing and they have good (when not great) quality.
I don't play with a steering wheel, so maybe I'm missing something regarding that aspect.
For me the shader stuff and the UI things that they talked about in this last video are more important than the Nordschleife or the Mclarens for the simple reason that it proves that they are intentioned to keep improving the game, so it's a long term support that they have in mind.
The nord was about to come sooner or later, so no big surprise in the end.
The McLarens were aready been announced. Same for Zandvoort.
The shader thing instead, for the way it has been described, could convince more modders to spend their time for this game. And this is what I'm personally interested in, because for me RF2 is already awesome as it is.
