We’ve had a couple opportunities to discuss the rumors of upcoming General Distribution Release updates for Windows Phone 8. The next, GDR2, should be just around the corner, and could be featured on upcoming models like the rumored HTC Tiara. GDR3 would be even farther out, and the big Windows Blue release would ultimately arrive after that. As we wait for official word on these updates, some new rumors are attempting to identify a few of the tweaks arriving with GDR3 in particular, including new resolution support.
According to sources, GDR3 will be ready by the end-of-year holiday season and will support the first 1080p Windows Phone handsets. So far, no specific 1080p models have been rumored, though HTC, for one, seems like a strong candidate for a manufacturer who might be up to the task of producing one.
Beyond the full HD support, GDR3 could also bring with it compatibility for new SoCs, possibly including some quad-core Qualcomm silicon. Frankly, that would make a lot of sense, since even with the low processing demands Windows Phone makes, drawing to all those extra pixels sure could stand the benefit of a chip with a modern GPU.
