2) Additional PS Move controllers cost $49.99. The $99.99 starter kit you mention comes with the PS Eye, 1 motion controller, and 1 navigation controller. Doing the math, for 2 players or the boxing game requiring 2 motion controllers would bump the Move price to around $150. For 4 player functionality, you are looking at 3 additional PS Move motion controllers @ $49.99 per controller bumping the total price to $250 ($99 starter kit plus 3 additional PS move controllers @ $49.99 each)
You are wrong on that one. Sony has confirmed that one eye toy cannot 4 players in full configuration meaning each players has a wand and nun chuk accessory. You can only have two wands or one wand and one nunchuk for one eye toy.
This means that you do after all need to buy a additional bundle for multiplayer games like boxing , archery and so on.
