Yes. Unless somehow a newer better version of the Wii U is out this or next year.
Not ever a good idea to get back a lot less then what you paid for only to re-buy a system in the future for the same price. Doubt the Wii U deluxe will hit $200 in two years.

I don't know if you'll regret the trade-in but It's pretty obvious that impatient people like you are dream customers for game hardware companies. You already bought your 2nd PS3 and some day you'll probably buy your 2nd WiiU.

I bought my WiiU early and as a patient person with currently 6 different gaming platforms at my disposal I'd even wait 5 years for the first Zelda HD, plus: Nintendo decided to give us Wind Waker HD soon and Pikmin will also (most likely) be released this year.

So even though I'd never sell my WiiU (or any other system) there's nothing wrong about your decision. You can do whatever you want, but keep in mind: Buying systems twice doesn't save you money. If you kept your WiiU and your first PS3 you would have saved money and woulln't always think about the fact if one of those systems was not worth the money.

The more systems you have the more choices you have (and you won't spend more money on games, you'll end up buying the best/most interesting games of each system).

You would've gotten more on ebay most likely

@bolded. Come on you can't really believe this :D

As for the topic:

First thing - don't let yourself get crucified by Nintendo fans here. Second thing, well i won't be very original cause a lot of guys said it before making decisions based on impulse, won't save you much money. But I can't blame you for what you've done and you have some good points. We know the PS4 won't be b/c and we don't know what the Gaikai compatibility will look like, so if you already have some games from PS3 library, getting a new one was definately a good idea(might I add the 500GB SS PS3 is the best SKU to get) i don't know which PS3 model you had in the past, but you basically upgraded it, so it should work perfectly for many years to come.

What I understand is that the WiiU was your only console. If you're tight on money and couldn't afford an extra PS3 then well...You're a gamer for god's sake and you were stuck with a system without a new game release for 3 months or so. That said it, was a good decision if you want to play games. What i think you should do is stick with this PS3 for good, at least until we will know what PS4 brings to the table in terms of b/c. Judging by your avatar and console pedigree you will end up buying a WiiU sometime down the road, simply do what I plan to do regarding the PS Vita, wait for the library to built up, a pricedrop and hopefully a redesing(please give us hdmi out for the Vita ;-( Ethernet port in your case)

So overall good luck and enjoy your PS3 and don't think about it and worry so much

Oh, I don't believe for either the PS3 nor the 360. This will be the last year both of them get significant releases. Sony and MS will both be moving on to their next systems and leave the PS3/360 behind (software-wise) once the PS4/Nextbox are released.

Thanks for shortening the quotation tree

Well fair enough. Of course it depends on what you would count as a significant release. I would argue that there is a good possibility of a similar situation that was present with PSP -> PS2 after the PS3 launch, but now with some late ports from the PS Vita to the PS3. I don't know how hard is to port a game from the Vita to the PS3 given the architecture differences, I guess it will depend on the adoption rate of the PS4, and how many units of software will the PS3 be able to shift in the coming year/s. All in all i believe we may see a game or two for the PS3 from first party next year/next years, and don't think we'll see anything for the 360, save for some Kinect stuff maybe.

Well let's end it here as it is slightly off topic. Cheers!

It was a mistake buying early as Nintendo like to screw over early adopters in my experience, then the second mistake was selling just as the games are finally due to arrive. Not to worry though I'm sure you made the right decision in the short term as there's some good PS3 titles due out.

So you bought a Wii U?! WHAT WERE YOU THINKING???

I agree with the people saying your biggest mistake was buying a Wii U so soon in the first place.

Consoles usually don´t have a great library of games in their first year on the market.

Ironically that should be true and probably is, however I really see no reason at the moment to believe that it is.  In fact all evidence to the contrary.  I've found around 40 upcoming games scheduled for release on the WiiU and for PS3: over 100.
