The Lumia 920 will get the Windows 10 Mobile update eventually. And you can easily update it to Windows 10 Mobile yourself using the insider program. It will not have continuum, as the hardware requirements for continuum require more in way of chip. Keep in mind that the Lumia 920 is over three years old at this point. It's a great phone, but certainly not up to date hardware in Q4 of 2015.
