Well here are the main things I see holding Move back:
1. No Sony identity on the product. The problem with taking the "safe" route that Sony did with motion sensing, is when you are too similar to another product you risk being compared to it. Comparison isn't good, as you want something to be different enough in a product to sell itself. When comparisons happen, not only effectiveness, but price and support will be a fact.
2. Needs a Big Sony title- I would love to see Sony truly show they support this thing by taking a risk with one of their bigger franchises. AKA, bundle a big game with it. Maybe, even make a game that only supports it. I know they don't want it to replace the normal controller, but if they want it to make a dent in the market, they have to go big. Maybe a new Ratchet and Clank game or GT5 support with an optional bundle, or something new they might announce. They can't rely on these current games they've announced, including SOCOM. They need something clearly Sony to sell this product. Remember Wii not only launched with Wii Sports but Twilight Princess as well. That was a good decision.
3. Effective marketing- once again another problem with the product not being something that sells on its differences, is they will have to market it as if it has huge difference. And because the controller looks alot like the Wiimote, it could come off as getting an "off-brand" connotation. Similar to Zune versus Ipod status. We all know how that turned out. Sony is going to have to effectively market this to ensure they highlight its strong points while trying as hard as possible to create its own market.
So yes there are some serious challenges for the Move, but I think most of it just come from Sony taking such a safe route with their motion sensing controller. Because it's safe I do think they will see some pretty good sales of the Move. Should at least do decent enough to get them rolling with motion sensing. But it's going to take doing the 3 things above if they really want to push this above and beyond like the Wii and potentially Natal. I personally will probably get one, as I do need and Eyetoy and this is a good way to get one.
