Wii - Already got at $279 (Cdn) which is about right, would only go up to $300 but it's actually dropped here to $259 (due to polarity to US $)
360 - $99 - I'd go buy it this instant. $199 - max price, $249 with desirable pack-in game(s) - Note: I won't buy until RRoD issues resolved.
PS3 - Currently would not buy (no games I'm interested in are out or coming out soon)
