True. Not only that, but the logo itself is incorrect, both on the uniform and on the ice itself...EA uses the classic Sabres logo, not the "modernized classic" logo the team has used for the last two years:
NHL 10:
(From Pebble19's Sabre dynasty, "City of Hockey"...if you look closely, that isn't the modernized circular Sabre logo, but the classic one. The logo on center ice is the same as the one on the jersey, as said before.)
Real Life:
Not only is the logo different (the silver outline and different shade of gold/yellow), but the colors, as pf8363 mentioned, are also different. Not to mention the numbers are a LOT thinner.
Combine this with the incorrect Sabres third in NHL 09 and the one-year-late change to the slug logo/jerseys, and EA hasn't had much of a good track record with the team. Although this could simply be blamed on the team itself and their tendency to unveil their new logos and merchandise immediately before the NHL preseason.
