Well, at the moment they have Killzone. Its not a system seller though*, which is why I'm sort of disappointed in SE's part. I want to love a Final Fantasy game again. Also having more exclusives can help, even if they are console exclusive.
*Maybe a PS4 bundled with Killzone Shadowfall and a Move will get me. It all depends on the price, which I expect by E3.
Edit: Also good thing I didn't get a Vita yet. Maybe I'll like the XL more.
