Here's one from 2003:
"...There's good reason to believe that a jazzy new Newton II will be forthcoming, perhaps in January" (Yup, that's our good friend John Dvorak).
Another from 2004:
"...[A US company] 'approached Apple willing to buy [the] Newton and relaunch it. They are in ... negotiations with Apple...'"
I think we all remember - and would like to forget - the iWalk.
Today, AppleInsider is beating this decrepit, old horse. According to their "well-respected sources," a team has been very busy at Apple building a multi-touch handheld successor to the Newton. Sure. In other news, everyone who paid $7500 for a Twentieth Anniversary Mac will receive $100 Apple Store credit, OJ Simpson is Steve Job's personal hitman and the next AppleTV will play Pippin games.
