I noticed that too. They have in the past had a kind of coat of arms on the left chest, with the NSWRL logo on the right (as you wear it), and I think this might be the first time they've had a City Origin logo in place of the coat of arms? Maybe not, as surely it would be strange to change it now in its supposed last year??
(I say 'supposed', as we've already had a final City-Country game years ago before it was brought back a few years later).
It is SO good to have the traditional Country jersey back too! I have loved it since I was a kid, and finally bought one late 2007 when I found one ... only for them to change the jersey completely for the 2008 season! My jersey is finally going to be current (bar the logos and sponsor)!
