Well I hope folks know that a couple of months after Nokia and Microsoft got together, Microsoft revised the standardized spec down from 1GHz to 800MHz, as well as they now allow both a dual core next gen Qualcomm and ST Ericsson chips. These are what Elop is talking about, concessions which Microsoft has made. This was made in a presentation at MIX11:

Also keep in mind that the current 1GHz will be the mid range devices by next year, the 800MHz is the low end segment, and the dual cores will serve the high end.

As for MeeGo not being able to scale as easily, their might be truth to it because with WP7 you obtain an OS that is optimized by MS for that SoC whereas MeeGo the OEM has to take care of that as well. Does that fault it although, probably not and he is most likely dumping on MeeGo for other reasons. The scale of the tie in with MS, and the amount they each are hedging on each other is probably what forced Elops hand. To get play in the maps service, I am sure MS said "no unless you drop Symbian and commit to us". This is what corporate negotiations are, you don't get anything for free and MeeGo is bashed because somewhere in the agreement it was a decision reached by both for doing business with each other. He will never publicly state this, that is why weak applesauce is coming from Elop regarding MeeGo. All agreements are forward looking, so consider his statements 2 or three years down. They would not hold true because by then MeeGo is more mature, the ecosystem is a year old, and engineers/ programmers are more comfortable with working on MeeGo on putting it on a variety of different hardware.
