Head to Toys R Us this Sunday morning for a Wii. Kotaku posted saying they're stocking up. At least that's how I got my Wii at Target based on a heads up from Kotaku.
Controllers were a pain though. Your local EB rep will know when they're getting stock; however, their stock replenishment is really low so after your local EB rep gives you the word head over to a large retailer nearby (for me Target) and check them out. You'll find lots in stock that same day.
