Watching.
Just announced a similar device
the LG L90 which is quad core 1.2 GIG processor a 4.7 " screen and outer dimension about 5.1 inches tall,so pocket sized, not a phablet, lol.
Bad news -available from LG as 5 megapixel or 8 megapixel Camera, TMobile selected the entry level 5,megapixel Camera !? ¿
Difficult to get medium sized Android with top features or even mid quality features.
Hopefully TMobile will carry the LG G2 mini and possibly the Galaxy S5 mini when available...
