@JohnBruso Well... I couldn't hold out for the new release after all. I got a 3 pack of M9's. Costco is to blame! $199 for the three pack and free two day shipping.

@JohnBruso Thanks John. After posting my original question I was able to find a resource on tp-link that helped answer the "which one to buy" question. For me the answer came from my ioT requirement....

I'm reading all the specs but still can't come to a decision. What'd be your choice? Re: M9, P7 & M5 I'm rural. My ISP can provide 25/4 & 50/5 Mbps. The house is 3000sf up, 2800 down & 1600 connected...
