Long story short...nobody knows, we dont know what Apple will do, we don't know the specs, we don't know jack.
 
well intel stated that they will not release i7 mobile processors until the first quarter of 2010 to help retailers sell the core 2 duo processor units... the i7 processors are about 7-8% faster than their core 2 duo counterparts. So any possible upgrade apple will do will not be too major until then I think.
