This is surprising news.
For the 2013 model year the Toyota Tacoma’s TRD Sport package has been discontinued but gets a touchscreen audio system.
One other source said a "limited" version is going to be offered. I wonder if it's basically going to replace the Sport?
NOTE: Information from all online sources (autoguide, motor trend, etc) are wrong. According to the official Toyota press release, it's only the Sport Upgrade package that's being discontinued. Credit goes to gunhound for spotting the error first (and it was only his 2nd post on TW).
