Hmm... I did some quick searches, because those numbers just didn't make sense to me.
Based on what I've found, the PS4 and XBOne use more than their slim last-gen counterparts, but much less than the original systems.
Here are some numbers that I found for wattage used when playing a game:
PS3 (60 GB launch system): 206 Watts
PS3 Slim: 96 Watts
PS4: 139 Watts
XBox 360: 187 Watts
XBox 360 Slim: 90 Watts
XBox One: 119 Watts
