Geesh, this is pure speculation. Stop worrying. N-Philes reported that GameSpot, or some online retailer, was taking pre-order for it for all the systems except Cube. Someone on their forums even wrote to the company who said they weren't denying the Cube version was coming, they just hadn't received official word. I'm willing to bet they haven't received official word on it for any console yet, but GC just got overlooked by some idiot in their web dept, now they're trying to cover up the error.
I don't know where the news that EA was taking the "No Comment" approach came from. They haven't said anything that I've heard, let alone "no comment". It seems like they're unaware of the whole thing. I was looking, and it does seem weird to me that the Cube version released last year one day after the other major ones. Why they did that I have no idea.
It is interesting to wonder just how important it is to the Cube though. The Cube version strangely does have the highest rankings from last year, but it didn't sell a ton. I'm pretty sure both Nintendo and EA can live without the 100,000 people who bought 2004.
