Not going to argue how feasable that many polygons would be, but the amount of polygons much rather depends on their complexity and that of the game itself than the generation of the game or the age of the console.
I'm sure developers could "easily" utilize over 50% of the consoles polygon max in a rather simple game. It's a simple trade-off, that's all.
