Verge saying no quad core
Sources: Apple TV update, iPad 3 for Verizon and AT&T LTE launching tomorrow, no quad-core SoC | The Verge
But that it's a go on LTE and apple tv3.
The only thing odd was Apple waiting on A6 for the iphone 5. If the A5X can power the ipad 3, then certainly it's more than enough for an iphone 5.
iMore says yes on quad core. So i guess we find out tomorrow.
