If the $199 bundle is the Wii, 2 controllers, necessary cables, and Wii Sports, I'm sold at launch.
If the bundle includes less goodies at that price (or higher), I will most likely wait for sales, coupons, etc and then make the purchase.
I like the idea of doing the 2600/NES thing and bundling the console with a multi-game pack. I realize it's not done now, but I think it's a good way of introducing the system to new users: my family played the 4-in-1 cart for the 2600 as much as they did any other, and though only me and a few siblings were big into SMB, everybody dug Duck Hunt.
I just hope they price it fairly. I don't begrudge Nintendo for selling me a tricked-out GC with a new interface, but I could become cranky if they try to goose me too much on the MSRP.
