Apparently the EOS will sport a similar screen resolution (768 x 1280) and battery (2000mAh) as the Nokia Lumia 920 and suggestions that it will sport the crazy 41MP snapper we found on the 808 PureView are still strong.
Interestingly enough the source also revealed that the EOS will arrive with a microSD slot - which will be music to a lot of people's ears - plus a microHDMI out and FM transmitter.
While these details aren't difficult to believe we're taking them with the usual side serving of salt.
It's not clear when Nokia is planning to launch its next flagship device, or if the EOS is indeed next in line to the Lumia throne.
