Sure, but that's also adding several years and a huge amount of development time/risk - it's creating a whole new spec, implementing it in both handsets and payment terminals, and deploying those updates. During which time, the non-halfassed standard will be chugging along just fine, increasing marketshare and generally not sucking.

It's technically possible, but one of those things that's deeply unlikely to happen, particularly given the lead that Apple (and, very likely, Android in the near future) and the credit card companies have in rolling out a solution.

EDIT: added a missing word
