What happens to the PS brand if the big 3 repeat their action next gen?

[Conegamer]

IF this happened (which is highly unlikely because I don't see Sony doing this again), then I predict LT sales (after 7 years) to be:

 Wii2-105mil

720- 65mil

PS4- 48mil

 

So the 720 doing about the same as the 360, Wii2 down about 7mil and the PS4 down about 12mil...
