I recently bought an Archer C1200 off of Amazon and noticed it is a C1200v3. I haven't had any luck finding any information regarding this version and if it is compatible with OpenWrt. According to the spec page located at wikidevi.com/wiki/TP-LINK_Archer_C1200_v3.x it appears to be the same as the C1200v1.2. It has 3 bands as opposed to the 2 bands of the C1200v2 which as far as I could see is unsupported. I was also wondering if I could use the Archer C7v2 version as the C1200v1.2 is the same spec wise as the C7v2 and was just limited due to the firmware installed.
