EXACTLY. I have a wii U too and it has the very same starvation problems. At this point in time, shoving out any security patch would be the final nail in the coffin. Ninty knows that, maybe a reason why no new system firm has popped up.
Also, not to forget, ninty is an entertainment company (unlike sony), I faintly remember one of their CEO's stating that they are not strictly tied to electronic entertainment, if they can make money with such simple stuff as dolls or figurines or cards (amiibo f.e.).
OK, that is nice to hear. Ofcourse it wont pop up tomorrow... but at least someone is doing prep work and has interest in the guts of a vita memory card.
@aos10
In your signature... is signhax / sighax already a thing? I know that at 33c3 the scene hackers stated to have hacked the 3ds completely and an important information was obtained in 2015 and ninty did not patch that.
Sorry for not being up to date here.
