Here's a list of devices that either have or will get Jelly Bean.
Also, this page shows a (fairly complete, though I hesitate to say "complete" for the fact that there's almost certainly at least one Android phone/tablet not mentioned on it that exists somewhere...) list of Android devices, including what version they run. It contains 41 mentions of 4.1 and 11 mentions of 4.2.
