This isn't my theory, I've seen it surfacing on the net ever since "Cabin Fever", but I think I can explain why people think this.
First off it's not just because they're both African-American. But that is one of the factors. On its own it means absolutely nothing, but with all the others things I'm about to list, they all make for a convincing argument.
1) Abbadon calls John, "Mr. Locke." And its not just that he says this, but also HOW he says it and how OFTEN he says it. If you go back and watch Season 1 episodes that feature scenes between Locke & Walt, you'll notice the eerie similarities and even the way Abbadon speaks, he has similar vocal cadences to Walt. Even in Abbadon's appearances in "The Beginning of the End" and "Confirmed Dead" he sounds like the way Walt speaks.
2) Abbadon sent the five good people on the freighter (okay we still don't know how good they are, and what Naomi's deal was), so if Abbadon is Future Walt, then he must have known that Michael was also on the freighter and was trying to protect him.
3) Walt really liked Hurley. Abbadon went to go visit Hurley in Santa Rosa in the future. Abbadon turned out to be a lousy liar (with the whole business card line). Walt was also a lousy liar (remember how Locke knew that Walt burned the first raft).
4) It's very possible that after living with his grandmother, the confused Walt went back to Australia to see his old home, and ended up going on a walkabout in the outback. This is where he found his purpose. I still really feel that there's a major connection between Australia and the Island. Remember Isaac of Iluru? Remember Richard Malkin? There's some crazy stuff going on.
5) Abbadon tells Locke a couple times not to give up. That is precisely the lesson Locke was teaching Walt when he taught him to use his mind's eye with the knife in "Special"
6) Abbadon tells Locke that he had a miracle happen to him. Well, Walt who had never known his real father, was reunited with Michael, then they survived a plane crash together, bonded, were separated, then reunited again and made it back to the US. That sounds like a miracle to me.
7) Abbadon also tells John that he went on his walkabout convinced he was one thing, but he came back another. Walt hadn't fully appreciated how special he is while on the island (of course we still don't know what happened when he was with the Others).
8) Abbadon tells John that he's a lot more than just an orderly. This is not just a way of saying that he's more powerful than John thinks, but also a hint that maybe John already knows who he is.
9) Abbadon says just before the scene ends, "when we run into each other again, you'll owe me one". In fact Locke helps Walt a great deal. Locke helped bring Walt and Michael back together when they were having problems on the island in "Special." Also, he taught Walt to realize his potential and he taught him to use his mind's eye. He also taught him backgammon.
