Being a "whore" is the way forwards with gaming. I go where the most stuff I prefer is.
I absolutely love the games I have on Wii U and definitely think the line up at the moment is better than the PS4 or XBONE. However I do think it's inevitable that PS4 and XBONE are going to have superior line ups within the next 12 months.
That said, the Wii U line up is so refreshing in comparison with the PS4 and XBONE, that like the Wii last gen, it makes a perfect accompanying system. This could well (at least for real gamers) prove to be it's secret weapon.
