Another point is that At the time of release of the WiiU the Wii was practically dead.
PS3 is still heavily supported which makes the people less ready to switch. So it will take a lot longer for the PS4 to get these people than it took for the WiiU to get the Wii audience.
Yep. Absolutely not comparable.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
