"EMV is going to render a lot of crappy, insecure technologies obsolete (things like Coin, LoopPay, NFC, and many of the smartphone based "wallet" apps.)"
WAT? Yes, LoopPay and maybe Coin will be rendered obsolete, since I know LoopPay is magstripe based and hence it's going obsolete in October.
But for the rest, "EMV is going to render itself obsolete" - makes NO sense whatsoever. Apple Pay, Google Wallet, and all other known NFC payment methods ARE EMV!!!! In fact many of them are more secure than the "plastic card" based EMV since both Apple Pay and Google Wallet use time-limited/geographically-limited or one-time-use transaction tokens, wherease "plastic card" EMV can fundamentally not be limited in time to anything other than the expiration date and can't be geographically limited.
In the case of Wallet, IIRC the method used since Google Wallet moved to HCE with KitKat is to generate a time/geography limited credential when you unlock Wallet with your PIN (which is why HCE-based Wallet needs a network connection for unlock, while the previous SE-based Wallet did not).
