Google's next poster child for Android Ice Cream Sandwich is to indeed sport a 720x1280 pixels 4.5" screen, which should be a sight unseen, considering the Super AMOLED technology. Utlization of the PenTile matrix means details won't be as distinct as they would be with a normal RGB one, but there will be more than enough pixel density to compensate.
The Korean source also regurgitated the rest of the info we've already heard about the Nexus Prime, like a 1.5GHz dual-core processor and October release. Considering that all these numerous sources point to Samsung as the manufacturer of Google's next reference Android phone, it will be interesting to see how the rumored powerful TI OMAP 4460 chipset is implemented.
Another interesting tidbit is that the Korean SK Telecom allegedly also plans to launch the Nexus Prime in its portfolio, which seemingly confirms the rumor that the phone might come to multiple carriers, instead of the usual boutique availability.
