It is from a Brazilian website, and as it would be pretty hard to understand the whole article, so I preferred to show the picture (scanned from Shonen Jump) instead. If by any chance you'd like to take a look at the article in which the picture was attached, just let me know and I'll post the URL.
Anyway, what's written in the news is that Valkyrie Profile Silmeria will be a prequel to VP, following the story of Silmeria, Lenneth's younger sister. It will be released for the PS2 next year in Japan.
While the screens are real or not, it is not for me to judge, but I can guarantee that the website from which the picture was taken from is highly reliable.
