I think this comparison is poor. 

3D largely defines what the 3DS is, I mean it's in the name, it's the "gimmick" if you will, and I don't mean that negatively.  Whereas the rear touch pad on the Vita is just a part of its controls.

Is it fair to speculate about the likelyhood of Vita failing now?

It's a shame that there isn't any coherent sales graph for less succesful systems like the Saturn or 7200. It would be interresting to see if Vita is following the same pattern or if it's doing better.

Not quite yet.

The line-up was supposed to dominate, when it didn't, it was Gravity Rush and Persona 4 that would save it, that didn't happen. Resistance: Burning Skies got mixed in there as well as MSG: HD Collection and Mod Nation Racers as possible "killer" softwares. But sales never materialized. (Uncharted still best selling title BY A MILE.)

Now it's LBP & CoD that will supposedly save it. If that DOESN'T happen, then yes, Vita will be an epic failure sales wise (and not just compared to 3DS).

It's needs a price cut yesterday.

A price cut will only help temporarily if the games aren't there.

I just want tomorrow to come, that's where discussions can really start. Hopefully VGChartz will update soon.

I, for one, HATE the 3D Glasses. Every time that I go to the movies, I have to pray that the version of the movie that I'm going to watch doesn't have 3D, or else I'll be nearly puking in the end of it. I'm not joking, this is the kind of headache that I have when I try to use those 3D glasses. But, when I'm playing my 3DS games, the only headache that I've had was when I tried playing Face Raiders while I was drunk. And it was just a mild headache, I didn't even need to gargle some aspirin to get rid of it.

I do agree that the backtouch in PSVita is a cool inovation. But, in my sick, twisted mind, the best application would be to sex games, and I kinda doubt that Sony would release something like that hahaha

And I'm a 3DS enthusiast, but I'm REALLY concerned for Vita's situation. The innovation (by copying - and somehow trying to improve - the concept of DS) is there, but I guess that it won't be enough. The REAL problem concerning Vita right now is what people already stated here: they must separate the feeling of playing something that you already played in your PS3 on your Vita, and they are still struggling to do so.

And give it a break: since 3DS released the Glasses Free 3D, laptops and smartphones are trying to mimic the 3DS "gimmick", so it's REALLY relevant. Maybe you're not attracted to it, but a lot of gamers (the old and the new) are, and it INDEED is an innovation. It will surely have some flaws, because Nintendo was the first one to try this. Other companies will do better, that's also true, but the concept was something to note for future generations.

Even it you don't like it (I'm not accusing you to be a Sony Lover, although sometimes what you say states it to me) the 3DS is a great platform, and these numbers are stating it every passing month.

The CoD release on Vita is going to be interresting to follow.

I dont know what websites you frequent, but I dont think anyone in their right mind thought that Modnation or MGS HD would do anything for the system. LBP either.  COD only if it doesnt suck. And Persona 4 did give it a boost in Japan.

But those two games you mentioned are not popular in the US anyway, they never were. I dont think MH or FE boosted any hardward when released in the US, so how do you expect those to help out 3DS if released in the US?? Whether they get released day and date of the Japanese ones, is irrelevant if most people dont care.   What 3DS needs more of is the games that made DS real popular, it already got the Mario Kart which is doing well. Nintendogs didnt do much, needs a cooking mama and Pokemon

A price-cut is needed regardless of how many games come.
