According to an EPL Talk interview with Pro Evolution Soccer brand manager Tim Blair, Konami is still looking into bringing PES to the Wii U.
When asked if Wii U and PlayStation Vita owners could expect a version for their respective systems this year, Blair responded with the following statement:
"At the time we don't plan to make PES for the Wii U or the PS Vita. This does not mean we never will. We are still exploring these exciting platforms to make a successful game that takes advantage of these platforms''
Pro Soccer Evolution 2013 will release on the Wii and Nintendo 3DS across all the territories later this year.
