Re:Nintendo's success. (Score 1)

if other developers...have to do too much downgrading to get their games to run on the Revolution that system is likely to suffer the same fate as the Gamecube.

Far from developers dumbing down for it, Gamecube was powerful enough that Nintendo wanted ports from the PS2 to be graphically enhanced. This generation, cross-platform games have to be playable at HD resolution on the 360 and PS3. Hollywood (Revolution's GPU) won't have trouble running such games at standard TV resolution.

On the CPU side, each of the consoles is a bottleneck for cross-platform games.

PS3 will have the worst general-purpose multi-threading performance, since it has a single PPE core compared to 360's three and Revolution's two.

XBox 360 will be the weakest in physics operations, assuming the PS3's SPE units can be used for physics. Revolution, with its dedicated physics processor, will be in the top spot.

Revolution will have the worst single-threaded performance, assuming it uses the same PPE units as 360 and PS3. This is likely given Revolution's low price point and small form factor. However, if it's instead based on PowerPC 970, it would have the best single-threaded performance of the three.
