It's now been three years since the initial QorIQ T5 announcement, and FTF Americas 2014 has passed without announcement of any specific T5xxx chip, and the subsequent QorIQ LS generation is at the ready with several chips announced, so I think it can be safely assumed that the QorIQ T5 has eventually joined the ranks of MPC75xx and MPC87xx (even though there are disconcertingly recent Freescale documents like this one (page 7) from January 2014 mentioning the 2.5 GHz QorIQ T5 as if it existed).
