Nope their problems are so different.
PS3's problem was Price...and poor marketing initially.
Also PS3 always had this "it'll blow up when this game releases" hype around it due to the inevitable GTA4, FFXIII, MGS4, GT5 launches. Of course we then got surprise 3rd party hits (Fallout, Oblivion, Assassins Creed, COD) & 1st Party hits (LBP, Uncharted 2 etc.)
WiiU has Mario Kart, SSB & Zelda left still....but with how Mario 3D World did things don't look so optimistic. And it's already got the first mover + low price advantage.
On the other hand with PS3, the first high profile exclusive, MGS4, sold in line with previous games in the series.
