Over at the C&VG, a blog post from Capcom was recently quoted to say that the decision makers over at Capcom are toying with the idea of making Street Fighter IV on the PSP. According to Capcom project manager Natsuki Shiozawa, she and many of her colleagues believe that it is the perfect game for the PSP.
I’m inclined to agree, although that depends largely on which model of the PSP you have. Players might struggle to perform the moves on the older models, but anyone with a PSP Slim or later (where the D-pad is vastly improved) shouldn’t have any trouble. I’d totally buy it, and it’s bound to work better than on the iPhone.
