On the contrary, I feel like they'd like to get up in front of everyone and tell them how awesome it is not to have a dGPU. Most people don't care about the difference so just hearing from Apple that it's better will make them completely ignore anyone who tries to tell them otherwise.
Now I don't think they're going to spend a lot of time on the Macs (just Phil getting up and saying "we'd like to show you our latest release of the rMBP" before they then go all out on iPhones and iOS), but I don't think they'll keep it silent. They want people to see that one little sentence in the CNN iPhone(-bashing, probably) article "oh btw Apple also released a new laptop" because then they go look at the laptop selection too.

If they'd been released in June I'd have gotten the 13", but now I'm getting the 15" as well. I saw the light!

As eneisch
mentions, the only AppleCare option for iPhones and iPads in the US is AppleCare+ (plus), which does in fact cover accidental damage. They do not offer AppleCare+ on Macs.
