Only info so far is the press release in case you haven't seen that here's an excerpt:
That's all the info we have right now but later about early to mid Aug Pioneer should put the model specs & features on their website. Until then "that's all folks"
Possibly because the press release is recent, and only covers new models (the 49TXi, 45, 43, and 41 are all new). the 49TX (no i) and 47TX have been out for awhile and don't need to be mentioned.
