A new device has just popped up on Samsung's open source site with the enticing model number GT-i9505G. For those not keeping track, the Snapdragon-packing Galaxy S4 is the GT-i9505. Samsung may have just dropped the kernel source for the Google Edition GS4 before the device is even out.
The same model number is also appearing in the Bluetooth registry, and there is a new WiFi Alliance certification for it. The hardware listing does look identical to the standard Galaxy S4, but that doesn't necessarily prove anything.
