ZTE U988S might land as the world's first Tegra 4 phone, see how it looks like
14

The handset is supposed to have a mighty 1.8 GHz Tegra 4 processor inside, which scores about on par with the feisty Snapdragon 800 chipset, and also enlist a 5" Full HD 1080p display, 2 GB of RAM, 13 MP rear camera and a 2 MP front cam, microSD card slot, and be pretty thin at 9mm. Android 4.2.1 has allegedly made it to the handset, and it might land under any number of aliases registered for ZTE lately, though Mustang is likely out of the question.
Thanks for the tip, @leakschina!
