Macbook Upgrade?

I was wondering if there was going to be an upgrade on the current Macbook anytime soon ? Im going to buy one around christmas, but I am willing to wait if there will be an even better one out soon.
Anyone know ?

They just updated them. Check out http://www.tuaw.com/2007/11/01/macbook-update/ for details of what was updated.

But will this result in lower prices for Canadian? Apple doesn't change the prices unless a new model comes out.

apple never really changes prices. they keep the price the same and then just up the specs of the computer
