...oh, they better not...I can't stand sticking with one hockey game all year. Whenever one game gets stale, I jump to the next and vice versa. Things would get much worse without variety on the market, trust me.
Remember 2003? We had Hitz Pro, NHL 2004, ESPN NHL Hockey and NHL Rivals 2004 on the Xbox alone (the PS2 I think also had Gretzky NHL Hockey that year). Now, we're only down to two games and people are clamoring for only one? Competition is good, regardless of how games rip eachother off, sports games have done that for years. Ask football/baseball/college sports gamers and they'll tell you. I'd hate to see hockey go down the same road.
