I cracked.
Just bought a brand new rMPB 15.4" 2.7ghz i7 16gb ram 512 ssd early 2013 for $2,273.69 after tax with employee 25% discount. MSRP $2,799 - $700 (25% discount) = $2,099.
Apple employee said I get a 14 day return policy no restocking fee. Maverick OS X update when it's released for free. Also if a new model is announced I get an extra 14 days extended return policy. Saved approx. $900 after tax (compared to $3100+ after tax and no discount)
So hopefully I'm safe just incase there is an announcement on oct. 15th but if it's on the 22nd Im out of the game. I honestly don't think they will update the screen at this point just optimize battery life and introduce better gpu and haswell.
