Its very expensive. Its a lot of money to just be able to play a few titles and these titles may or may not be of questionable quality. Comparing the cost of a single DS3 and the opportunities it brings for two player gaming, the value is obviously in favour of a DS3 over a $100 Move pack.
I am suspicious that Sony won't have any truly awesome games for Move until next year and the adoption rate will be a slow burn which will probably be enough to see to it that anyone who buys a Move pack will likely be disappointed by its gaming opportunities given the proximity to the next generation.
The PS3 will not be the Wii HD, the next generation Nintendo console will be just that. If you want to save your pennies you may as well go next generation Nintendo than slum it with the PS Move.
Tease.
