While we're just hearing that an entirely new version of Google Wallet is on the way (what exactly is new about it is what we don't know), Google announced via Twitter that MetroPCS is the latest Wallet carrier partner. The Galaxy S III is the only Wallet-compatible device on Metro for the moment, but you can probably expect most future Metro phones to carry Wallet support, as well.

If you're keeping count at home, that brings Wallet support up to three carriers: US Cellular, Sprint, and MetroPCS are all now official Wallet partners, US Cellular being a recent addition we reported on earlier this month.
