Well, cetain design elements are different but that's pretty much the Isis I remember.
A quick story: I had a friend who was absolutely livid over other comic book companies' "stealing" of Marvel Comics' Thor. When he told me he was going to write Savage Dragon's Erik Larsen because he had the nerve to even name the hammer, Mjolnir. Furthermore, Larsen couldn't even be bothered to get Thor's hair color right.
I explained to him how mythic characters like Thor and Hercules aren't quite subject to copyright and that only the concepts that Marvel introduced within the Marvel mythos... no, actually, I just farted in his mouth while it was open and just walked away.
HA! Made ya look!
So, what I'm wondering is this: As far as I could tell, DC's never actually owned Isis outright. She was a character created specifically for television and DC went on to get the license, producing eight issues of the comics version. Has DC's gone and spent some of that good ol' Identity/Infinite Crisis money they've been making and gone and bought Isis or have they just licensed it again? Either way, I want to go on record as supporting any move, incorporating more raven-haired, mini-skirted women characters into comics.
