I contacted Pentax USA here is their reply...
Thank you for contacting Pentax USA, Inc.
At this time we do have the Spotmeter V in stock and we are expecting more
of the digital spotmeters in soon. While it may be possible that Pentax
Corporation in Japan will discontinue them, we have not been advised of that
in the customer service department.
We hope this helps
