Nobody knows what's different between an RT-AC1900 V1 and V3. The fact that they both appeared at the same time makes me suspect there might not be any difference and this might just be a packaging quirk. I can't see Asus going through three major revision within the course of a few weeks.
Thanks for setting me straight RMerlin.
I'll stop guessing on this now.
