I have no clue what direction they'd want to go in though... I wouldnt think it would be another throwback, but at the same time I have a feeling they'd keep the orange and blue over any copper and blue designs.
It's pretty rare for a jersey unveiling to go this long without any real publicity. Usually teams have to submit designs for a style guide that is given to retailers and the like before the season starts. Another board I visit has users who have access to style guides and it just showed the Oilers having a home jersey and an away jersey. It has been rumoured that in 13-14 the Oilers were supposed to have a new alternate jersey.
But, I wonder if the Oilers pushed the NHL to have the jersey a season soon to surprise the fans because of the lockout. That wouldn't surprise me one bit... and really, if that is the case, a nice little financial gift to the organization as well, as I'm sure the appetite for NHL merchandise is high right now coming out of the lockout.
