the price for 3G sku really depends on the 3G provider. They can offer $100-200 discount with 3/5-year contract of a data plan. It will substentially reduce the price for the 3G sku.
Actually, there may be a chance that the 3G sku costs less initially than the wifi only skus. The only thing, I think, Sony needs to convince people to buy the 3G sku is to enable Skype on NGP...
