Anyone know what the back to school deal will be?

Walmart canada has the m2 air for $599 right now. I'm debating whether I should just buy it or wait for the back to school deal on the m3. Performance wise, I guess there will be little to no difference? But if the back to school deal is a gift card that makes the prices similar I'd wait I think. If it's just a free pencil, it'd be worthless to me since I don't plan on buying one anyways.
