No, game over, there is no chance. And the sooner you accept that the sooner you won't feel upset and frustrated when you'll see Wii Us weekly sales.
I was once in your place, I once thought the Vita may be a success, I waited and waited for the sales to pick up, waited for 3rd parties to show up, only to see sub - 40k weeks and some obscure japanese games, tops. After some time, I think the tipping point was an NPD report with Vita < 25k and I embraced the idea that Vita failed in the West, and you know what? It set me free. I take the Vita for what it is, everything above is a bonus. Weekly sales aren't dissapointing anymore.
And the more people accepted that, the less Vita doom threads popped up, cause there is no disscusion when everyone agrees, it becomes beating a dead horse which is boring. It's only up to Nintendo fans how soon Wii U doom threads will dissappear. Right now I'm waiting for another batch cause Nintendo fans hoped Donkey Kong will be a success story.
