Am also very interested in this mismatch. And there's another problem. I've never seen any of you @sinovoip or Foxconn guys showing a picture of any of your boards with a heatsink on it.
Both M3 and M2+ are prone to heavy overheating. Do you really never test your boards under real world conditions? Do you care about settings like these: https://github.com/BPI-SINOVOIP/BPI-M2P-bsp/blob/ce11facf03efb8cc1b2f84d220e0a371baba9ba1/sunxi-pack/chips/sun8iw7p1/configs/BPI_M2P_720P/sys_config.fex#L414-L418
