Well, that is not a reliable source.
Rely on Horror consists of normal gamers just like us, none of them works for Capcom, and it openly says "Rumour" in the title.
Don't get me wrong, I
hope you are right (and at the same time I hope not, because it would **** me off to know there's a new Claire game out there that I can't play because I have the wrong platform again), but I wouldn't bet on it. Fans are just desperate to see Claire again, that's why there's a rumour about her every few months, and the predictions of Jorge Bocanegra (the author of your article) are always interesting to read, but rarely come true. (For example, he thought Chris would die and Sherry would turn evil in RE6.)
When does the WiiU version come out anyway? Or is it already out?
