I emailed the Sixers. Their official response was that it was that next years uniforms/logos were yet to be finalized.
We will not be returning to the red, white and blue uniform full-time this year. There are select dates where we will continue to wear it for the remainder of this season (weekend games and the March 13 game at the Spectrum), but will be rotating through our current uniforms throughout the rest of the season.
A final decision on what direction we will go in regards to any uniform/logo treatments beyond this season has yet to be finalized.
That leads me to believe that it's at least being discussed, otherwise the response would be like it was last year (which was the retro's will be used at in select games).
