Did gow, ratchet and infamous collection bomb that hard? or vgc didn't track them?

Three undead platforms (PC, PSP and the new undead baby, PSV  ) doing well this week, interesting. Haters Exorcists, paladins and other enemies of the dark forces will be pissed-off!   

Guess this proves that Vita simply needs software and nothing more.

Just a note, I'm going to need a soundbite for console performance this week.

go guild wars 2,madden 13 the holidays are coming

The Vita had already many games, but they don't help much. Next week the sales are down again ...

And for such a big game like Hatsune Miku the sales are only meh.

As someone who has been around and seen the trends here for about 5 years, I can tell you with utmost sincerity that it's lacking games.

The games you've referenced above, prompted Vita to sell at a rate completely unexpected by most of the industry. Those games did their job by securing great sales.

Then, like you said yourself "next week the sales are down again". Those games don't keep selling the system forever. A system constantly needs new games which then develops the library. They need new games because new games sell systems, especially big games. Vita specifically hasn't had big names in a while except for the indie-ish game gravity rush.

At a certain point all the people who exist that buy consoles for a single game...run out. You then have to rely on your library to sell systems. Vita's library has been what has sold the system the past several months. That 35k per week has been based roughly on games that have come out 7 months ago. Every game that is added to the library sells maybe another 300 units per week, and maybe a thousand consoles for a big game. The math isn't complete and there's some gaps, but the idea is that you get a library of 20 AAA games, and 50 AA, and 100 A, and you're selling ~100k consoles per week.

You might vehemently argue this but I mean, there's really nothing to argue. I could simply show you the graphs depicting this exact thing happening in the past for every single console that exists. You build up your weekly sales with your library, and madden and miku proved that there are still very many people willing to buy a system for a single game. I mean, who buys a console for Madden. Really ask yourself that. If Madden can kickstart sales 400%, guess how much good games would accomplish.
