You need to look at the differences between launch sales and lifetime sales. You need to look at the growth of the fanbases. You need to look at things in perspective, not just the lifetime numbers.

ZombiU as you can see from the link was a bomb. It didnt profit.

AC3 sold 220k at primarily bargain bin prices. It sold less than 85,000 units in its first 5 weeks on sale. It was not a success for the franchise.

ESPN I asked a question.

AC4 is a bomb on Wii U for the same reasons that AC3 is. It sold less than 70,000 units in its first 5 weeks on sale, despite the franchise developing a fanbase on the console with AC3. Ubisoft also didnt think it was worthwhile releasing the DLC on Wii U. The late port PS4 version sold more in 24 hours in America alone than the Wii U version has lifetime. Perspective. 

Marvel Avengers sold 70,000 units. 15,000 of them came in the opening 5 Weeks. Im not sure how anyone can call this a success.

Splinter Cell is a bomb end of.

Your Shape: Fitness Evolved 2013 sold around 40,000 units. Every other game in the franchise passed 1 Million units. Its a bomb.

Smurfs 2 as I said, bombed on everything.

Rabbids Land has sold less than 10,000 units. Its the lowest selling Rabbids title by a giant gulf. It sold so bad that VGC tracking for it isnt even Weekly. Its a bomb.

According to Yves Guillemont himself, porting games from Xbox 360/PS3 to WiiU is very cheap: 1 Million Euros or so.

That would make 50k units the break even point for WiiU ports.

lol so many people said that it would be not a surprise 

I googled that to make sure and youre right. Ive probably seen it before somewhere but it totally slipped my mind if so. Im quite surprised. Thanks for bringing it up!

In which case, you could probably remove the AC titles from the list.

Uh, assuming somebody is interested in playing Watch Dogs, why would buying a PS4 to play it be strange?

It's basically guaranteed to have the best version of any console.

I think the two can co-exist.

Honestly would it be a surprise if a multiplat game without a release date yet had its wii u port canceled? I think it would be sad, but not too shocking considering similar things have already happened a few times.
