Right now, what I can see, it looks like joeykrim and noobnl and a couple of others or so are cracking away at it. Most of the "action" seems to be happening over at sdx atm.
Unless some of the devs from the other galaxy s phones come over here and share the love, I think "we" might be on our own (so to speak). I saw a few placeholders for roms in the dev section. They might be doing stuff behind the scenes too.
Now I don't have too much free time on my hands. One thing I was pondering was if someone gathered the info from the other galaxy s phones and tried to determine what, if any, might be similarities under the hood. Like was rooting different, same or similar between models? The only apparent difference seems to be the epic has flash led and hardware keyboard. I don't know how much those two things could possibly change the structure of things (hardware and software) between all the models. I suspect there will be quite a few similarities after the dust settles.
