Yes, but it's still crappy IGPU any way you slice it. But then, I guess Apple assumes (probably correctly for the most part) if you want something in the 13" range that's extremely thin and light, you're not looking for a graphics powerhouse.
Although, assuming that's the case, I'm not sure why you'd choose Retina vs. 13" Air, except for the pretty screen. With what you can configure in terms of CPU/RAM for either model, I'm not sure the Retina will give you THAT much more horsepower for anything truly "Pro".
I have an 11" Air, which I love. But I've never had a problem with the "old" 13" MBP form factor. In fact, I liked it a lot. Just small/light enough, but could throw in a huge/fast SSD and 16GB RAM. My complaints were the crappy GPU and even crappier resolution. I'm fairly certain they could have fit a discrete GPU in there. And I'm positive they could have put a higher resolution LCD (seeing as how, they already sell a 13" laptop with a higher resolution screen).
I don't care whether it's "retina" by their definition. Put a discrete GPU and 1680x1050 LCD in the current 13" form factor, and it's instant buy.
Trouble is in the 13" form factor a discrete GPU is going to generate too much heat and kill battery performance. This is why I would have liked to see it loose the optical drive, go only slightly thinner (ie thinner display) and add a discrete GPU with bigger battery rather than making it super thin which for this size of machine is not of much benefit over the Air. Though I have to wonder, in this size machine who is going to be doing lots of graphic intensive work. The HD4000 is capable of multi stream HD video and only really lacks in 3D performance. I would have liked to see more RAM as an option but again as a developer I have very specific needs and Apple probably have a load of market research pointing to the spec they have just introduced. After all the 15" rMBP sold like hot cakes and I suspect this one will as well.
