The need for native mobile exporters is getting more urgent every day!
Well I think the opposite. The need of native import is less important everyday now. C2 biggest problem comparing to other engines is the performence for mobiles apps. It's because whatever you do in C2 your output is HTML5 and then you have to wrap it to whatever you need. Now keep in mind that even though you can't build very big complex mobile games with C2 due to the performance issue, you still have a tool which lets you build apps in the fastest and most comfortable way on the market.
Imagine now what will happen in a year or two from now. Power of newest mobiles like SGS6 is higher than the average 3 year old laptop. In a year from now SGS6 will not be the newest and most powerful, it will be the average. What I mean here is that day by day we are getting close to the time where performance limitations won't be really a problem for an average user.
Now keeping pressure on Scirra to make a native export is pointless. It would be a tons of work for them to implement something like that. And even if they'd decide to do it, it would probably take a year or two. So there is no point cause in that time wrapped HTML5 will work fast enough anyway.
Now regarding Cocoon IO and IntelXDK. I see there are people voting for and against. Eeach of them has a reason. It looks like it depends on the game itself, plugins used etc.. So if your game release is a serious thing then just take a shot and test both.
Noone is complaining for no reason, that's clear. Both XDK an IO have some issues. But then again remember that it is not forbidden to use any of them. You do have a choice.
It reminds me the old times before W3C actually started to do their job. All browsers had their own rules for parsing/interprating CSS,JS and even HTML. That was a real nightmare for frontend developers that time .
Now we have one project in C2 and it behaves differently when you wrap it with IntelXDK or others... I believe there will be a time soon where it will be obvious what to use OR it will have no matter what to use.
