At this point WU will beat PSV globally by a huge margin by now.
Is what is happen last year. After a "not bad" PSVita starting, the sales are massive dropped, and WU is starting not only to beat Vita, but even XBO... that's what is gonna to happen again.
WU will beat PSV every week by now (maybe PSVita can win just 2/3 weeks by a smaller margin WW when a huge JP game will released), and WU will sell at XBO level... (50k-60k)
By holidays, XBO will starting to sell at beasting level in the US (above PS4) and very well globally, menywhay WU will beat PSVita lifetime.
