A lot of you made a lot of noise about whether or not we would get Ice Cream Sandwich (4.0), but having used 4.1 on another device, I can tell you that the move to 4.1 is a much bigger deal than the move to 4.0, particularly in terms of performance!
The source cited is HTC's Russian Facebook page, this may only apply to devices made for/sold to parts of Europe.
Ah well, at least the people who make 3rd party firmware will be able to get the proper drivers and whatnot. Perhaps it will be time for me to learn how to root when one is made for the EVO 3D.
Thanks for your response!
