It really does seem like everything that happened in the 3DS' early days is playing out again with Vita, though for now these sources remain uncorroborated (though Nikkei has been fairly reliable with insider info, barring a few missteps)

A story was written for Nikkei by Kiyoshi Shin, the head of Japan's IGDA branch. In that story, he claims a major game industry source had this to say.
"Major Japanese companies are canceling all projects intended for the Vita and are changing development to the 3DS."
Obviously Sony says that's not the case, but you have to wonder how much Sony wants to let on while the system is yet to fully launch outside of Japan.
Everything old is new again...
