Then you'll notice that its for the PS4 version only, even though there's a physical Vita release. The US NISA store seems to be offering a Vita version of the Grand Edition, so what's going on? The EU press release mentions on a PS4 Limited or Launch edition - I'll try and get an answer!
UPDATE: NISA got back to me and let me know that Grand Kingdom on PS Vita will come in the various editions, with the limited ones only available from their store:
- Standard Edition: Available at select retailers and the NISA Europe Online Store
- Limited Edition: Available exclusively at the NISA Europe Online Store
- Grand Edition: Available exclusively at the NISA Europe Online Store
