I think it would be obvious. All the major publishers would be aware of what's going on, though that's all heavily clouded by NDAs, and the propensity of jackasses to dilute the information so that any real leaks are treated the same as rumor
Certainly Ubisoft is aware of Nintendo 6th, Nintendo Handheld 5, Xbox 3, Playstation 4, and PSP2, but that doesn't have to lead to anything.
Though a new Nintendo handheld in 2010 would explain a lot of things.
