The interesting part is not Solo Mode vs. Group or Open Mode. The interesting part in this is PvE vs. PvP. I haven't seen the stream yet, but from wha you wrote it's very PvE centric content that gets added in horizons.
Xbox players not having the option to create their own private groups. Horizons very PvE centric content.
Hm, Open PvE mode on the horizon?
The only interactions that a SRV can have is between 'bases', skimmers around those bases, or other players shooting from their ships and SRV's. It seems to be very group oriented, with the capability to be able to finish the same missions in Solo....albeit with more care and thought and skill than a group dealing with the same content.
I do not see this as PVE centric. It is just ground based USS's really. Get down to a planet find something, either kill it or collect it, and return to base to collect a reward for the mission. It appears there are options for some gameplay, such as
buggy SRV Racing, in a Mario-esque kind of way (shoot each other as you drive, jump, fly, flip, etc. your way around a course). But more fun with people, than without. <shrug>
TBH, if FDev wanted a PVE only mode, they could already have it. I still believe they do not desire that..and if they decide to do that...it would change the game drastically for a lot of players.

Given that the game is sold as, among other things, a single-player game, I would not expect the cord to be cut. That'd be bait and switch....
Sorry...I meant for the Solo players to cut the cord...not FDev...will repair. Fixed.
