If anything, it shows that all there's all kinds of ways to market your game and if it is enjoyable, people will pay for it.
Now, looking at this year's possibly popular indie games, I think Crayon Physics Deluxe will be a hit, and I hope Fez (video here), which I haven't heard of since February 08 will post some news, and finally there's Braid again, which is coming on the PC!
Additionally, if you include game mods as indie development, I'm looking forward to Neotokyo, a total conversion mod for HL2 that has its inspiration in Ghost in the Shell, and Black Mesa Source, another total conversion for HL2 which is the original Half-Life ported onto the Source engine.
