Brawl will indirectly help 3rd party sales by forcing Nintendo to ship more Wii's to cover the brawl launch. The more hardware sold in a month, the more software is sold as new buyers buy games to take home and play. As a result of additional hardware being shipped for Brawl, software will be up across the board for the month of March on the Wii. And that will benefit both first and third party sales.
This scenario is amplified in effect when you are talking about a console that is supply constrained at retail like the Wii is now.
