A coyote costs about $6200, and the ecm and harness are about $1500
http://www.fordracingpartsdirect.com/5_0L_412HP_2011_MUSTANG_CRATE_ENGINE_p/m-6007-m50.htm They've both been available from Ford for over a year now. Google 2011 mustang if you want to see what all tuning and hot rodding you can do to a coyote.
The previous link has a dyno chart for the coyote, it has 100 HP and 250 TQ at 2000 rpm estimated. A stock mustang 5.0 was rated at 205HP and 275TQ PEAK. A slightly warmed up 5.0 dyno charts
http://www.allfordmustangs.com/forums/5-0l-tech/309749-my-bolt-302-dyno-results.html At 200RPM it has less than 100HP and around 200TQ estimated. I don't see the coyote being a dog, and haven driven a new F150 with a coyote(385HP), it isn't.
Chuck at BC BRoncos has put a coyote in a bronco, he said it was a tight fit, but a 1" body lift and slight right fender trimming was all that was needed.

The ICON bronco uses it own frame for its own reasons, but one of them is so they can claim to have their own "newly designed" frame I bet. Several people have swapped mod motors into broncos without major surgery.
I have looked into building and will be building a bronco with a coyote, and have talked to several people who have done coyote swaps into various vehicles, including broncos. Is it a direct bolt in, no. Is it a fairly easy swap with a few considerations, yes.
If you are looking at doing a efi swap on your motor at time of instal, you will cover a large part of the hard part of the coyote swap.
People have had similar arguments going from horse an buggy to motor car, Flat heads to OHV motors, FE motors to windsor motors, and Carb to EFI. Chose to swap what ever you want and have fun.
Now excuse me, I have to go finish cutting the rear half of the body off my trail bronco off with a sawzall and cutting torch.
