This here is why this new ninjhax will not do crap for Gateway. There's no way Gateway needed ninjhax 1 to be released just to do their exploit, kernel exploits take a long time to find and a long time to develop into a usable product. They would have had to know about gspwn well in advance in order to develop or even find the arm11 exploit used. The arm9 exploit was probably less difficult for them to find though. Most people now only want Gateway to develop a >9.2 exploit so that it can be stolen and used for CFWs, and this also is exactly why I'm personally predicting that Gateway will either drop out of the 3DS game or they will continue using and working with firmlaunch hax. Why would they spend the time and money looking for a new exploit only to have it be stolen with little profits going towards them?
And also, with the whole "ninjhax led to 9.2 exploits" thing again, causation is not necessarily correlation. This isn't the Wii where a new entry = complete access, entrypoints and kernel exploits are completely separate things. Having new entrypoints doesn't do crap towards Gateway finding new exploits, OoT has been a viable way to explore kernel exploits for them for the last several years probably. It always will be viable. And like stated above, the only reason to even look for a new exploit is purely to get N3DS emunand back to the latest version. Getting a 9.2 or below o3DS is super easy, N3DS less so but it's possible. People searched for 4.5 o3DSs for the longest time and GW still turned a profit, the same story is present here, except there's CFWs now which most people will go for instead of GW. So basically any chances of having 9.9+ support have already been burned by all the piracy CFWs which were released.
