A French website claims that a unnamed Nintendo of France marketing employee has leaked information about Nintendo’s second generation Wii system. The rumor has it :

Market competition has given birth to a new and improved Wii console rumor since the launch in 2006, so again with a tight economy world wide for all video game makers, the grape vine is once again at work.
One more interesting addition is that Nintendo will have a trade-in system, Wii owners would be able to upgrade to Wii 2 and get a break on the price.
