Yeah, I hope so too. One thing about the D and E especially will how expensive will it be to purchase the amount of cargo required to fill them up. It might very well be outside of a single individual ability to do.
Also it might have a lot of guns, but how fast is it, how manoeuvrable is it. Even with guns, the cargo is exposed, so the cargo will take a lot of damage unless it has an escort to keep them at a distance.
At least those are things I am hoping for. Heck for all we know you might bring your Hull E somewhere and it might takes a few days before it's loaded and ready to leave.(You do other stuff while it's being loaded)
I am hoping that solo trading is more limited to Freelancer, Hull C and smaller, or Constellation type.
I think they have enough ships, of different size that they really push for the need to have multiple player run mission with the larger one...not just to crew them, but to escort them.
So about 1M this weekend for the new ships. It's really insane how much money people are putting into this with the game still so far off and being mostly nothing but promises at this time.
