Yes, the article favours Nintendo, and we're all fanboy....ish here, so we like it.
But all in all, I think it's an incredibly even-handed analysis of the market as it stands. I don't think he missed out on one element of the industry. He also avoids looking into the 2010 crystal ball that keeps coming up in other articles, where they say that the PS3 will dominate in three years time.
But everything, from analyzing Microsoft's failing strategy, to the costs of risk to high production cost games, to the DS to Wii transistions for successful titles... everything is in place.
If I were Sony or Microsoft, the one thing I'd walk away with from that article is the importance of the low-buget gaming industry. It's the testing ground for franchises which *then* you can decide to spend millions on for a home console version. We learned it from Pokemon, Trauma Centre, Cooking Mama, Wario Wares, Batallion Wars, and the list goes on. We wouldn't have half of the franchises we do today if designing a game for GBA or DS cost more than the half million dollar pricetag they run around.
