I dunno... I mean it's actually smart to not make this a single board machine with built-in GPU, since there isn't really a workable open GPU / display controller solution. So making it a PCIe host that can take any off the shelf GPU neatly solves this problem.
I have high hopes that sifive might be able to make something happen here.
IF RISC-V ever gets big enough for economy of scales to kickin.
PicoRio is aiming at the Pi price point, but its specs may be lower.
