CES 2012: eBay CEO (and new interim PayPal CEO) John Donahoe, revealed at his CES keynote yesterday a number of new mobile payments forecasts for not only eBay, but PayPal, too. PayPal VP David Marcus said a few days ago that PayPal had surpassed its expectation of $3.5 billion in mobile payments in 2011, reaching $4 billion for 2011.

Donahoe said in his CEO keynote that eBay reached $5 billion in mobile GMV (gross merchandise volume), this is a 100-percent jump on 2010's GMV. Donahoe also projected yesterday that eBay would reach $8 billion in mobile GMV in 2012, with PayPal reaching $7 billion in transactions in 2012.

Mobile has more than 65 million downloads of eBay's mobile applications across all platforms. More than 890,000 new eBay shoppers completed their very first eBay purchase via the mobile apps in 2011, an 113-percent increase year-over-year. Donahoe also announced a new strategic partner in eBay's RedLaser barcode scanning app, who is it? Well, it's Best Buy. The app was updated last fall to include integration from PayPal and Milo to give users the ability to buy now for either in-store pick-up, or home delivery later.

Best Buy joins Toys R Us as RedLaser's latest partner.
