They're not picking sides, and developers don't get to make decisions like that. Let's put this into perspective. Watch Dogs was due for release in November last year, and a decision was made to delay it for fine-tuning - a tough decision, because it meant missing having it as a launch title for PS4 and X1, and risking an operating loss at the end of their financial year. The company's share price dived by more than 25% at the time. Source

It makes you wonder what state the game would have been in if it had launched in November. Whatever we might speculate on that, Ubisoft clearly didn't consider it was up to the standard they wanted it to be at the time, and delaying it to deliver a higher quality game was evidently considered worth losing out on those things.

Don't forget, every month of delay loses money, both in lost revenues and development costs. Now they've got everything ready to go for all platforms except the Wii U. It seems to make sense to release what they have ready first, and delay the rest until it is done.

And anyway, is it fair to Wii U owners that they get a lesser version than everyone else for the sake of releasing at the same time as everyone else? Everyone has already waited. The Wii U owners will have to wait longer. Yes, it sucks, but making consumers wait for a decent product is not screwing them, and it's not unprofessional.

What is unprofessional and disrespectful is making consumers pay good money for a glitchy or sub-par game that could have been fixed if given a few more months' dev time. And clearly, Ubisoft are doing everything to make sure that doesn't happen.

(edited for clarity)

Depends.

I don't care that much about delays or what's happening on other consoles.

The quality of the product matters the most and I ask myself if the game is worth my money.

I wouldn't buy a port like AC3/4 at full price months later (when you can have the PS360 versions for 30 Euros). The price would drop to PS360 levels within a very short time and I'd buy it for a reduced price (like most of the late ports of the Wii U launch were at PS360 prices in spring 2013).

But a well-optimized port with good GamePad features and added DLC could be worth the full price for me (although I hate that Ubisoft games lose their value so quickly).

Doesn't matter what he expects if he lives in never-never land.

OP is off his rocker.

What I learned in BUS 101, the main aim of a business is to maximize the wealth of stockholders. By being professional they are doing their job to maximize wealth. None can blame them.

So how do you propose they make PS3/X360/X1/PS4/wii U/3DS/Vita/PC/OUYA/Android/ios versions all at the same time?

the install base goes out the window, when you consider that there are less Xones out there than WIi Us and Watchdogs has less preorders than the former. So its not really a userbase thing not totally. As for the bolded, if Ubi games keep flopping you bet they will drop support or at least lower support. Danm near everyone else did. Never said that they needed to be in the top 30 to be preordered. BUT if you're not in the top 30 i would bet that those arent large preorder numbers. Hence Watchdogs

Rayman is not a great example, becasue 1 it actually was on the charts, for the Wii U but taht was befoer the delay. It didnt have large numbers. 2 Rayman has always been more popular in Europe. guess which company between Sony and Ninty is more popular their? 3 we dont have preorder numbers for Europe. Rayman was going to always do better on PS3. 

Its not really off topice we are talking about Watchdogs for Wii U OP is saying that Ninty gamers shouldnt buy Watchdogs for Wii U and im saying dont worry alot werent going to anyway. Im using the preorder numbers to show how little interest their is for that particular SKU. Unless you believe that Watchdogs has a chance to do as well as any of the other versions? But you dont believe that. Hell it will sell as well as UBI's other games which is not well at all.

Why don't you read my post and try again? I was not "defending" EA. I was talking about how Piracy is wrong and hurts more people than just some scumbag exectuives. 

never mind all that when one system is doing fantastic and another is doing terrible, WHICH one are you gonna prioritize. When will people discover that resources are not infinite.

You don't need to say anything. From what I've seen and heard, Ubisoft is going to do a whole lot to win me over to fork down $60 bucks.
