The true boost given by MK8 for the Wii U will definitely only become apparent in June NPD. 2 days of data is certainly not enough. Only friday and saturday and not even a full weekend. Based on how the SW sales went also, initial adoption was by those who already had the console. The wii U sales also definitely hit a new higher baseline for at least 2 weeks in all regions since then and persists in some like France till now. The boost for the US should be apparent in the next NPD. Whether that is enough to finally save the Wii U is up in the air. And that doesnt change the fact that its a brilliant console that some of us absolutely love to bits and that the PS4 is still hype fuelled.
