Was it known that Riku is playable in Kingdom Hearts 358/2 Days?

Was it known that Riku will be a playable character in Kingdom Hearts 358/2 Days? If not, check out this promotional page from V-Jump:

It's for a Kingdom Hearts 358/2 Days guide book. Titled Kingdom Hearts 358/2 Days Heart Collection Guide, the book is due out on May 30, priced at 1,150 yen.

The big point of note, as pointed out at this blog, is the text to the bottom-left. It says that readers can look forward to a guide to 72 missions through Day 295, along with strategies for mission mode characters including the Organization XIII characters, Riku, and Donald.

That would seem to suggest playable Riku!

You might also remember indirect confirmation of Sora from a while back.
