Calling it graduating is about as retarded as one can get, but as a long time gamer, I'll say this plainly.
If someone buys a Wii, gets into gaming, and buys a 360 or PS3 to see what else gaming offers, I am 100% behind them in that. If they start at Wii Sports, move on to Galaxy, move to Call of Duty, and come back to Bloom Blox, all they are doing is experiencing more and more of this hobby that most of us love.
Mebbe, try saying something like this: "In this generation, more and more people are finding gaming accessible and fun as activities to enjoy by themselves or in a group. Nintendo has done good job of targeting multiple demographics that normally aren't targeted, and we believe that with our diverse Xbox360 lineup, more and more consumers that have enjoyed the Wii, will purchase a Xbox360 and find out just what gaming with Microsoft is all about".
See Ya George.
