I’ve gotta’ imagine it is probably going to be streaming. I can’t see how they’ll deliver that level of detail otherwise. Perhaps it’ll have an option to download and cache regions? But, even then, folks with bandwith limits or paid bandwidth are out of luck.
It’s hasn’t been stated either way. I think @Tim_N was expressing it as a concern. And, yeah, no VR would make it a tough sell for me no matter how beautiful it looks. but I also have concerns with delivering that level of detail at 90+fps and high res. Here’s hoping!
