Make of this what you will, but according to a few tweets from some keen-eyed overseas fans, Amazon Japan created a page for Rockman DASH 3 over the weekend -- a possible sign that the retailer is gearing up for pre-orders.
Though it is pretty bare bones at the moment, the very existence of the page certainly seems to warrant the above notion. There's no indication that pre-orders will be accepted soon; however, customers are encouraged to sign up to be notified when it's a-go.
Admittedly, It's a little peculiar that Amazon would list a game that's supposedly not even green-lit into production yet... but it couldn't hurt to keep an eye out on this one. After all, Amazon is a pretty reliable source when it comes to release date/window leaks.
Thanks for the tip, Jason!
