I'm pretty sure if there was a decline, it was because of the summer market.
But looking at ebay, people are still paying retail price and more, sometimes 300$ (also plus shipping) for a wii. It's possible supply constraint still exists.
I for one will only be picking up one M+.
I also don't think they keep supply low to generate buzz, but rather Nintendo tends to under supply in order to maximize profits, with the added benefit of generating buzz.
