"Muv-Luv Trilogy PS Vita version won't be canceled!
We're aware many people have been waiting for the PS Vita games, while we cannot give any definite date yet, we can reassure everyone that Degica will always support the PS Vita! We already have released cool games, and more to come :)

The majority of our PS Vita backers pledged for the physical rewards with a PC digital, so delivering the physical rewards as soon as possible is our top priority. We'll immediately resume porting to PS Vita once Muv-Luv Alternative PC version is completed."
