I'll believe it when I see it personally. Of course a Vita dev is going to big up the struggling device. They're hardly going to say 'We're not happy with the Vita, and we don't think you should buy one and our game either', because it's bad business. It's only logical to big it up; they'll get more sales.
And it's obvious games are being made for the Vita. Good games. But it's silly they haven't announced them yet. Unless they're going to release huge game alongside the WiiU launch, like how the 3DS got Monster Hunter the same week as the Vita launch...
