While it seems to be going in the direction of pilot error, it is still very early on in the investigation. I know after the BA crash people were saying the same thing days after the investigation.

That being said, there a plenty of links in the chain leading to the accident. Fortunately most were saved, who otherwise would have perished as a direct result of the cabin crew, fire fighters, rescuers, and, last but not least, a durable Boeing product.
