$this->bbcode_second_pass_quote('WarheadsSE', 'I')f the RPi3 (ever) becomes ARMv8 capable, this will no longer be possible.
I believe it will still be possible after 64-bit software is ready, since the configuration is also on the SD card.
In other words, the file /boot/config.txt is what determines 32-bit vs. 64-bit mode, so as long as your RPi2 SD card doesn't enable 64-bit boot (which it wouldn't) then when that card is in the RPi3, it will continue booting in 32-bit mode.
