I think no handheld console can live well in the west nowadays because of smartphones, except nintendo consoles, mostly because it appeals to large public like child or women, without this public, i'm not sure 3DS would do better in the west than Vita.

Sony will talk about vita at e3. Give it a price drop

Would you guys be expecting Vita.tv news?

I don't understand what you mean by increasing their investment if they make game they will surely increase their investement.
Can you explain me why Activison make ghost on wii u when black ops sale really bad worst then call of duty desclasified.

Well like you said not much effort was put into the PSV by western third party publishers. As a result their games havent sold well. Because their games havent sold well and the system in general hasnt sold well...they wont be investing in the platform beyond what they are already doing. What are they currently doing?

- porting console games

- releasing spin offs (some good some bad)

- some devs not supporting at all

Theres nothing enticing the publishers to put in more effort/more money into the platform. New AAA IP's tailor made for the system! Nope none of that. AAA spin off titles! Nope not much of that either.

That is what i mean by "won't increase their investment". Activision probably wont be releasing an amazing AAA COD on the PSV anytime soon. Or what about a new IP FPS made specifically for the Vita? EA probably wont release a ground up PSV centric AAA Fifa or any sports game for that matter. Ubisoft will probably just release liberation 2 with the same scope as the first. And so on etc.

Third parties will probably just keep doing what they doing. This wont help the system any more than it already has/hasnt.

Advertisement is important.  How do consoles get game support?  By generating an install base.  No advertisement=no sales=no games.  No advertisement means Sony doesn't want to invest money in the console.  They're giving it the smallest amount of support possible and it shows.

As for games, the only games Sony is making for it are...

a) Indie games with a shoestring budget.

b) Ports of PS3 games that take minimal effort and resources.

c) Killzone: Mercenary and Tearaway.

Seriously, those were the only retail exclusives developed by Sony and released in the US.  They also published Soul Sacrifice (in the US I think) and Epic Mickey (for some bizarre reason). 

By contrast, Nintendo cut the price on the Wii U when they saw it was failing way quicker than Sony did, advertised it more heavily, and produced more games.  Wind Waker HD (a port, but still completely remade with a new engine and all before you compare it to something like MLB the Show), Pikmin 3, Game and Wario, Super Mario 3D World, Wii Party U, Wii Fit U, and publisher for Wonderful 101 and Lego City (which were totally funded by Nintendo unlike something like Epic Mickey 2). This is also a newer system where game releases typically tend to be slower.  The Vita should have worked through its drought by now.

I'm definitely not trying to say the Wii U is doing well, but Nintendo is doing a lot more to support it than the Vita.  In the West, Sony is supporting the Vita as little as possible without outright discontinuing it.  They're trying to keep it alive mainly as an accessory for the PS4 and as a Playstation Now device in the future. 

This is a stupid way of thinking i not talk about you but about third party.

You interpretation of why third party don't support vita is like a student who had an exam and didn't put any effort to get a good mark when he get his result he had a really low mark and then decide to abondon his study he never think that if he made efoort before the exam he would get a really good mark and continue his studies.

When you don't make effort at anything you will never succed.

Activision could at least port ghost on vita just like they ported it on wii u.

I think you didnt see the games coming in 2014 to say Nintendo support more Wii U, at the moment, Vita has as much first party games coming ( Freedom Wars, Oreshika 2, Soul Sacrifice Delta, Murasaki Baby, and Borderlands 2 published by Sony like many others ) + much more 3rd party games coming on Vita, so i dont think we can say Sony support less Vita than nintendo support Wii U or see it as an accessory.

No need to have a huge install base to sell games( persona 4G/Ys Celceta are a good example compared to the previous on PSP), the games create the install base and publishers know that, this is why it's getting more and more games from Japan, they see a lot of people are interested to play their games on Vita.

it is 3rd-party developers ignoring Vita that causes it always have nothing much to show rather than Sony ignore it... 

We don't yet know what's coming out in 2014, but if you're trying to compare the Vita's lineup to the Wii U's, you still don't have a leg to stand on...  The only game you mentioned that's actually being developed by Sony is Freedom Wars (and they have two other studios working on that) because Sony does not want to use their developers for the Vita. 

Wii U has Mario Kart 8, Donkey Kong Country Tropical Freeze, Smash Bros U, X, most likely Yarn Yoshi, and will fund/publish Bayonetta and Hyrule Warriors.  These are larger projects, most of which are being developed by Nintendo themselves (or Nintendo owned studios) or at the very least are solely funded by Nintendo. Of course, things could change over the course of the year, but based on what we know, Nintendo is putting far more resources into the Wii U.

And yes, you do need a large install base to sell games.  Persona 4 Golden sold 600k copies.  That's not enough to create a thriving market.  And that's the exception to the rule.  That's the highest selling Japanese developed third party game, and the third best selling third party game overall.  Those sales are going to be unacceptable to all but smaller Japanese developers.  So you'll see support from those guys, but few games will be localized.
