I have a Wii. Can I still use Rock Band World?

Rock Band World is the companion App for Rock Band Blitz, which is available on the Xbox 360 and the PlayStation 3. If you are a Wii Rock Band 3 player, you can still use Rock Band World to track your Rock Band 3 stats and peruse songs, but you will not be able to use the large portion of the App which is dedicated to Rock Band Blitz interaction.
