I'll clear it up even better for you, then it's football time!!!
MBP's the fat ones apparently, 13 and 15 inch will be dropped next year and the Retina's should take their place. The 13" Air will be the replacement for the low end model, I do not count an 11 inch laptop for 1k. 1k goes a LONG way with normal vendors, for Apple you get an 11 inch with a 64GB SSD... yeah.
The line is thin but thats the way they like everything so there ya go.
Ah, your using your crystal ball, I see. Your also making a completely different point. I also think that eventually the Macbook Pro and the retina model may become one.
