"Hey Siri" support and possibly wireless charging case alongside AirPower charging mat.
Of most interest is word of that one company is conducting a survey about Newton technology:
"We need to determine why the Apple Newton was not a commercial success and whether there is an interest in re-launching a new version of the Newton," the survey says. "Your comments will help understand why the Newton failed and if there is interest in re-launching a new, improved Newton."
The Apple Newton was first introduced in 1993 and essentially represented the first Personal Digital Assistant (PDA). The Newton went through various revisions over the years but was discontinued in 1998.
Apple, however, retained the rights to all Newton related technology, and at least some has made it into Mac OS X (Inkwell).
