He didn't bought it with gaming in mind, because he has a X360. He got a low-end Pentium core 2 quad, 4GB of Ram and a crappy GPU.

Lated he decided that it was better to use his money to upgrade the GPU instead of paying for Live and DLCs. Now the only X360 thing he uses is the controller to play on the PC.

You are missing the forest for the trees, but I’ll get to that later. Nobody expects Sony to throw their full weight behind the PS3 after the PS4 launches (in fact the division of their resources has already begun). They’re balancing their resources between the PS3, PSV and PS4. It is inevitable for them to mitigate support for the platform over time, but it won’t happen overnight, and more importantly that’s not the point of this argument. The point surrounds opportunity cost, and the OP would be better off gaming on the PS3 since it has games NOW and the Wii U has NOTHING of note at this point. Furthermore, it doesn’t seem like the Wii U will have strong titles this year, and the REAL reasons to own a Wii U will likely come out next year. With that said, the OP can use the PS3 NOW since it has GAMES to play and upgrade to the Wii U later – either next year or the year after when it has games and is cheaper. Instead of focusing on that detail of the PS3’s support dwindling over time you should look at the bigger picture here (the forest).

As for PS3 support, I think you’re overlooking some details here. To think all of their studious will switch to PS4 overnight is a bit naive. Are you aware the great majority of Sony's studios have at least 2 teams? Are you aware that the majority of them are doing PS4 games while the other sections are doing PS3 games? (Take Gran Turismo for PS3, PS4 and Vita for instance). Sony wants to extract as much as they can from the PS3 before it is obsolete, and Sony won’t be the only once since other devs will want to make as much as they can from the larger install base before committing wholeheartedly to the next gen platforms. I think we’ll see cross-gen titles akin to Watch Dogs and Assassin’s Creed IV for a while before they transition completely, and I’m willing to bet a lot of those titles won’t grace the Wii U. So far it seems only Ubisoft is willing to support the Wii U, for now. Oh and as for the Xbox examples you used with Microsoft ... there's little consistency in your comparison since MS was not interested in supporting the system, at all. They just wanted to launch first at all cost and cut the life of the Xbox after 4 years, and that's happening now with the 360 (to a degree). You may not believe Sony plans to support the PS3 after the PS4 launches, but I'll take the word of the VP and guys at the World Wide Studious over your perception.

At the moment, no there no reason and the more we hear how devs are praising the 720 and PS4, ....I don't see a future for the Wii U. Exclusives are great ,but for the gamers who don't buy multiple consoles, its simply not a good investment if you'll be missing out on killer multiplat. I learn my lesson with the original Wii and I'm scare I might had made a mistake buying the Wii U too soon. I guess because it was Christmas and I got caught in the hype, which I hate.

Regret is a horrible thing :/

Some people are taking this personally. LOL. But your biggest mistake was trading in the PS3 for the Wii U in the first place, still dont know why the hell you did that. But it seems you learned your lesson, dont buy a console just cause of a name on a box at launch. Doesnt matter what name, that will always be a foolish decision. At least you rectified it by getting rid of Wii U and getting another PS3, a system that has a lot of games. YOu could always buy Wii U later when they have games you actually WANT to play and it might be cheaper.
