I don't get posts like this, or why anybody would wait for a Vita version before jumping in. PS4 was the perfect platform for S&S, hence why it released there first, and S&S isn't 'just' a Vita game. Don't be fooled by the art style, this game is as good as Dark Souls 3.
For me, I knew I would only play this on Vita, I just don't fire up my PS4 all that often unless it's a massive game or something my friends are really into online. (I'm just a portable player at heart.) So until I got solid word that the Vita version would reach completion, I was appreciative but not quite ready to pull the trigger.
(That said, a good sale price on the PS4 game could have made me buy in, I do believe there are other games I bought on discount and just haven't downloaded yet because my backlog is a nightmare and Vita is my only hope of churning through my purchases.
Also, if it has any value at all to the metrics (I'm sure they could see download numbers as well as sales,) I'd like my purchase to be counted as a Vita purchase in the PSN storefront. Vote with your wallet, they say, and I am a registered and dedicated Vitacrat.
