David,
we have ESP31, alias ESP32 beta, this are the boards that was given in beta programm
and we have the finally ESP32, just in time there are no finally ESP32 boards on market and comes with mass production Q2/16
( Q2/16 means: quartal 2 year 2016 means: [april, may, june] 2016 )
ESP31, alias ESP32 beta do not support just in time CAN,
finally ESP32 support CAN
and like Greg said,

Will release on next version SDK. Too many things on-going now.
the work on CAN is just in time.
for your better understand
hope this helps. There are ESP31( ESP32 beta ) and ESP32 diagramms.
ESP31 support no CAN, where ESP32 support CAN.
( see GPIO 23, same, ESP31 have no ESP 23, ESP32 have GPIO23 )
think, the question will be detailed more:
Have we CAN as Controller, as Transceiver or have we CAN as Controller and Transceiver,
either or both later in ESP32.
and this is would be a more nice infos, what we have next time. i think normaly we can have both, but i am not sure.
perhabs Greg can answere this next time detailed.
best wishes
