Going completely mobile looks like a very bad move. All it is going to take is Sony or Nintendo releasing a 4G LTE capable handheld, and a good marketing champagne and mobile will see a massive fall in gaming.

Android and iOS are the worst platforms for gaming, and it will take years before they ever reach the Game Boy level of games. Even that could only ever happen if they actually gave an once interest in games.

If Sony and Nintendo build handhelds that can replace smartphones for 10% of the mobile market, they will make more money off games from that 10% than android and ios make from the other 90%. Real gamers need to support real gaming devices, that offer real controls, and actual thought and innovation. Between Windows Phone, PlayStation Phone and Nintendo's NX platform, I think Android and ios are in for a massive collapse over the next five years.

It seems that the only ones that might be the safe ones are the self sufficient ones. The companies that know how to pinch pennies, produce good high quality games and attempt to diversify.
Mobile is VERY trendy. Many mobile gamers don't really care too much about who develops a game unless they garner the title of a high quality developer. EA is on the list not because they create good content but because they have some long standing franchises that they are milking to death on mobile and they are large enough to put a new game out each week and not a lot of money is put into them. In many ways it seems quite soulless, although the same can be said for some AAA console titles as well. It seems the most soul is coming from indies lately and they are likely the future on consoles. They are far more diverse than Konami has been in many many years and given the choice I would take indies over Konami, Capcom, SE (as it is now, not back in the day though).
A big part of the issue here though, is that the consumers (you and I) tend to push for bigger, better, higher quality graphics ect ect and we don't really buy enough to justify the hard push for it. I'm speaking in general here, not each individual specifically. This is why we get so much consistent usage of the same engines or similar games over and over again. All the COD's, AC's, Dark Souls/Bloodborne/demons souls, Elder Scrolls/Fallout, GTA, Mario Kart, Smash ect ect. Some of these games are absolutely great without doubt, others... Not so much. But unfortunately it doesn't leave a whole lot of room for other games since these each up so much consumer money when there doesn't seem to be much to go around for some reason.
Anyway, it's a sad day.

how to put this low costs and high returns , easier and faster than AAA
but tbh with strong established ips, it will be easy to make money off these

cheap investment high returns less risk than AAA

however the market is unpredictable, however with strong established IPs it wont be an issue making money

Its a fad. When developers will understand it will be too late for them. Konami, SE and Capcom etc dont know that yet.

A fad that has been gone for how long, about 5 years? 

Established IPs sometimes have hard time making the return. Hence why you even have video game companies making mobile games.

By fad I meant "one hit wonder" games. Not mobile platform. BTW does anyone know "rovio" now a days?

Oh I agree with one hit wonder games. Rovio still is some what relevant (they do still make variety of angry bird stuff for multiple platforms), just not the top dog anymore. A lot exist in the market, but some companies like Activision and EA have found huge success in mobile platform with multiple titles. 

I honestly don't understand why people like mobile games so much. I don't exaggerate when I say that Cookie Clicker represents a perfect example of what mobile game essentially are: Just doing the exact same simple task over and over until the games says "Good Job!" and then scales up the difficulty immensely so you buy more extra lives.

In the past, things like game balance, progression speed, and difficulty was designed in order to maximize the entertainment value of the game. But with mobile games (and rather worryingly, newer games on PC and console), game balance and pacing are dictated by what makes the most money, not what's the most fun.

If you can't make a fun and in-depth game, you won't get a dedicated audience. And with no dedicated audience, you can't get a firm footing in the market. That's a big part of why the mobile games market is so unstable.

Mobile could become very irrelevant anyways if playstationNow is launched
