I found this link that I think I'm going to have to follow up on (and explains why there's a // gs browser image on 16sector...)
Note that the 16 Sector page has been up for a while and that the guy that owns/runs it is a very trusted Apple // enthusiast. Whatever is coming, I'm sure its no joke.
It appears to need a pretty beefy GS configuration but Ewan Wanop's Spectrum Internet Suite appears to be the browser shown. It's not new but it does recommend both a 4M+ machine and 3.5M of disk space and mentions that an accelerator would be a seriously good idea.
The reports I've heard from the site owner is that we have to wait until Kansas Fest to find out! But that doesn't mean I'm not going to keep looking and wondering!
