I'm still a little dubious. I think that if there was plate tectonics, it was very limited and not planet wide. I also think that most of the evidence stated in the article can be explained by a Tharsis uplift that did not include subduction and plate movement in the Earth sense.
But it is great that they are gathering more and more information and putting it together.
