Don't worry though. It's not as bad as you think.
Nintendo "cannot promise" that all online services will be free of charge no matter what, as reported by Nintendo President Satoru Iwata during the recent investors meeting.
"[Nintendo] cannot promise here that Nintendo will always provide you with online services free of charge no matter how deep the experiences are that it may provide, but at least we are not thinking of asking our consumers to pay money to just casually get access to our ordinary online services," Iwata said.
On PlayStation 3 currently, the PlayStation Plus service allows users to pay to get a new selection of games to play every month, in addition to other premium features. Meanwhile, the regular PlayStation 3 online access remains free-of-charge. It is unknown if this could be the kind of plan Iwata is referring to.
