I'm going to preface this with a few notes:
1) This isn't the script Calgary is using, just a very similar font. I'll work out something later when there's a better quality image to work off of
2) This by no means is a perfect jersey.
3) Ignore the font selection for the numbers and nameplate. Those are just quick placeholders.
So here's what I'm hoping we'll see. Taking into account that this could have just been a old rendering EA used as a placeholder, I'm hoping the final version had a couple tweaks along the way. But here's what we can assume will remain: Black shoulders, that awesome alternate logo, and 'Calgary' script. That taken into account, this is what I hope we'll see:
If that's on the ice, I'm not too upset. No major changes here, just little tweaks here and there. The yellow bands are thicker (understandable to assume that EA just hasn't represented this properly in the game), dropped the flaming 'C' (could have just been an early idea), and added a few details to the shoulders (could have been added later before final production).
Edit:
Alternatively, if you find the back too busy with the added details:
