It can be in japan. It's that important. Of course, something like Soul Sacrifice can become a monster hunter sized phenomenon, but it's difficult to predict those things.  Quite a risky bet, for any game. That's why I said they're relying too much on not having it.

Well, that's what I think. Maybe it's not the end all, but surely it can be.

I put it to you that if a new Final Fantasy or Dragon Quest got announced for the Vita, sales would go up. Exactly the same if these COD rumours come true. Monster Hunter is not the only game in the world.

It's not. But when I say Monster Hunter, you can substitute it for any big japanese franchise (all the... 3 of them that are not first party). But MH is even bigger than those, especially since Dragon Quest is very hard to happen on VIta.

But best selling games in PSP are not new IP and this will not change with Vita.

That's true. Having those options are nice indeed. But to me, if most of the titles are just multiplatform, then original titles like Gravity Rush won't be released. I'm sure they will eventually and that's what I'm hoping for at E3. Not a Vita version of most PS3 games already known like Playstation All-Stars and LittleBigPlanet Racing.  

They were not new IPs, but they were new games with all new experiences.  What Sony is attempting to provide is the exact same game and experience ported from PS3.  I have no problems with playing already existing IPs on a handheld as long as I'm playing a different game from what's on my home console.  There are very few people in the world that would benefit from transfarring and exact ports between Vita and PS3.  It's an extremely niche market, and Sony would be better off providing each region with their most wanted games as soon as possible.  If they announce Monster Hunter Vita at E3, that would be the best thing to happen to their new handheld so far.  And if they also come up with a big Call of Duty game for Vita, that would be just as good of an idea.  Turning things around in a couple of weeks is completely possible, and the Vita can still have the success of the PSP.

This. Pretty much what I'm saying.

They are like Loco Roco and Patapon and in Vita Unti 13,Gravity Rush thost new Ip won't outsell Fifa or Uncharted.

Over-reliance is such a strong word; It is not vital but cross-platform is definitely a feature everybody should appreciate. It would certainly be appreciated if we receive definite new IPs regarding such feature but it's not Sony's fault their audience are deeply captivated with rehashed IPs with similar genres.

Conservatively, Mario (etc) is just appropriately well-managed by Nintendo. I suppose what sells well is what organizations tend to focus on. It's capitalism.

Like others have said this article makes the assumption more crossplay games means fewer original games. Of course this is actually the opposite because these crossplay games will sell systems while new ips can gain popularity.
