Oh wait, Wikipedia says 'drop-in replacement' and 'copy of the original device', which would mean DIP but possibly also original speed (but we'll have to wait and see I guess).
Looks like the speed will be unchanged. "According to Paul Gerrish, President at Rochester Electronics, the company has acquired all of both companies remaining finished devices and wafer/die as well as intellectual property in order to manufacture
the exact same device and provide a reliable continuing source of the devices for systems that continue to use them." From the same link I notice the article is dated 2014. But the Wikipedia info is more current: "At the end of 2015, Rochester's MC6809 was into fabrication with expected production starting in July 2016."
Some fresh 6
309's would be nice!

But you'd wonder if there's enough demand, especially with the 6809 being re-introduced.
