I do fear that it's reaching the limits of its potential, though.
I'm not too sure. FS is all about portable code that can service many platforms, so who knows how deep 'down to the bare metal' they are programming (CPU and GPU). Even though there is absolutely ZERO piracy (excluding the old PSP games that run in the sandboxed emulator) on the VITA, a feat which is shared by the Wii U (*), I'm very unimpressed with the available knock-you-off-your-socks-when-you-see-it software on the platform.
(*) Some people can dump Wii U games but they cannot be used for anything. PS4 and XB1 are 'too new to count'.
