Hmm i actually think i am going to wait for the next refresh then.
If it is really true that Intel has stopped making the westmeer (core 2 duo chips) and sandy bridge is out in Q4 2010, then i might as well wait for octovber/febuary and see how it is then.
we might even get a case redesign
You are wishing for too much I think. I was in your position before. Since their 2009 refresh came out, I played the waiting game and was disappointed when the 2010 refresh came out. They kept C2D and minor updates.
You won't be seeing anything until 2011 so October, November, December are out of the question.
And a case redesign?!?! Not a chance. Apple is sticking with this unibody design for a VERY long time. They don't change body designs THAT quick. They kept the Powerbook body the same as the Macbook Pro body until 2008!!!
Maybe in 2013-2014 they will change the body but not anytime soon.
