1. It is a good idea. However i think that there will be an issue with price, affecting the quantity of consumers buying this product because there is no other 13" mac option. And as for the price drop of the 15" retina macbook pro, i have high doubts this will ever happen right now. The way i see it, macbook pros probably will have retina as standard and a lower price point a couple of years down the line, as there are less bugs and rising competition from other big companies out there. So i could agree with you on the fact that the non-retina macbook pros will phased out at some point, but now isn't a good time to.
That is a possibility. However, you should remember that Apple discontinued the 13-inch white MacBook, which sold for US$ 999, in favor of the similarly priced, low-end, 11-inch MacBook Air. I don't have the figures, but I suspect that the 13-inch white MacBook was one of best-selling Apple laptop computer (and perhaps the best-seller). However, people didn't stop buying Macs and they moved to the other models.
Something similar may happen again. Apple may push the 13-inch Air towards consumers, and the 13-inch Pro towards pros. There is no sense in keeping two 13-inch laptops at the same price point, especially when the features of each other will eventually converge.
2. yet again, i can agree with you on this, but what will the markets reaction be? $1499 - $1799 is still quite a lot for any computer today, even if it is retina, and this is why the bananas are are still not ripe for the picking yet. I reckon the 15" retina is an experiment, and then it will be standard in a couple of years time, like i said before, when (i) apple will have had the time to invest in cheaper ways of making retina displays, and (ii) apple have made a big enough market to buy these new machines.
Yes, US$ 1,499 - US$ 1,799 is a lot for any computer, especially a 13-inch thin-and-light. However, it would fill the gap left by the 15-inch model.
I don't think the 15-inch retina is just an experiment. I think it is the first of a new line of MacBooks which will soon take over the current ones. The current design is almost four years old, it's about time for a refresh. Retina displays are not as expensive as one might think - the iPad has a 2048x1536 display and sells for US$ 499. Apple could put a retina display on its 13-inch models and continue selling them for the same price - or just a little bit more expensive. There's just no sense in charging more than US$ 1,000 for a standard 13-inch laptop with a 1280x800 resolution and that still uses an HD.
As for keeping the 13" air on the market - what is the point? If apple continue to make their designs of their macbook pros thinner, and they also add retina as standard, you might as well just phase the airs out and add an 11" macbook pro retina to their existing line of MBPs and call it a day. the one-up macbook airs being sold today can be upgradable to 512GB flash storage, and 8GB RAM, and a 2.0Ghz i7, and that is something i call more pro that air-ish IMHO.
Yes, Apple could do that. But will it? The thing is, the MacBook Pro has a faster processor. If Apple is able to put a standard-voltage processor inside such a thin package, it may just keep the Air. However, Apple may also want to take advantage of the low-voltage Haswell processors which Intel will release next year, and which will allow for great battery life (just 10W).
Apple could keep both a 13-inch Air and a 13-inch Pro with a retina display, putting them at different segments.
carbon fiber, while making the design lighter, makes the design disgusting and very un apple-ish, whether it has the brand logo on it or not...
I don't know. It's just speculation. Carbon fiber makes laptops lighter. Lots of companies are using it, and Apple is probably looking at it right no. Apple may well find a way to make it look nicer.

what screen resolution would the 13inch macbook get if its released?
Also I voted for october, its what all the rumors are pointing to.
2560x1600, probably.
