True, but he was only referring to dedicated gaming hardware in the first post.
If you remove the PSP, PS3, PS4 and Vita, you're left with the 3DS and the WiiU. So you tell me, i dont see whats akward with that question. If you dont want to include the WiiU either, then you're left with the 3DS only
The 6 month time frame was just an example, feel free to add your own timeframe if you mean that the Vita software support has shown sign of decrease in recent times.
About the other things you say, thats fine, but where do you think that the support will be moved to? That is basically the only thing i'm wondering about.
