Yes, from people who owned PSPs and saw the Western third party support start off pretty "meh" and dwindle down to virtually nothing.
And given the higher costs of developing on PSV, and the lower profit margin on games (thanks to it using carts), I think people have every right to be skeptical of third party support.
And a handful of ports at launch is hardly evidence it will get strong third party support from the West. Let's see how it's going in 3 years, when the PS4/Xbox 3 is out, and quick ports are no longer easy.
