VITA has virtually ZERO Exclusive Third Party games announced for next year!

[Kresnik]

Valhalla Knights 3 + Senran Kagura as you mentioned.

A very poor showing indeed, but not quite ZERO !

I agree it's a problem for Vita though, indeed.  There's too much up in the air with it at the moment.

edit: btw, your second link doesn't lead anywhere really.  Just the front page of gamefaqs.
