The 13" rMBP dropped $400 off the price between revisions. If this rMB were to do the same, it'd slot perfectly into the $999 price point. Apple is selling this first version at a higher cost to amortize R&D, then they'll be able to sell a newer version at a lower price. That's what I think anyway.
So you think they are counting on refurbished models to sell at the $999?
I don't think so. They need to sell brand new laptops at $999, not used ones.
