If you're a fan of the DS demos on your Wii's Nintendo Channel, consider this your heads-up to check out the channel at least once a week.

Some demos that debuted with the channel's release, including one for the oft-overlooked but excellent Ninja Gaiden: Dragon Sword, have already been removed from the service and replaced with others. Other lost demos include Jam Sessions, Rayman Raving Rabbids 2, Cooking Mama 2: Dinner with Friends, and Disney Friends. New demos have taken their place include The Spiderwick Chronicles, Apollo Justice: Ace Attorney, Eco-Creatures: Save the Forest, My Word Coach, and Iron Man—though all of the above are set to expire on the 18th, just three days away.

It seems that third party titles are most likely to fall out of rotation; Nintendo's own Brain Age line as well as Flash Focus and Crosswords DS appear to be immune from expiry, for now.
