Original story: The Singapore PlayStation Store has published a page on Mega Man 11 with an October 3rd, 2018 release date. Not only that, they've got a full description for the game too (including a small bit about the "Double Gear" system) Check it out:
"Mega Man is back! The newest entry in this iconic series blends classic, challenging 2D platforming action with a fresh look. The stunning new visual style refreshes the series' iconic colorfulness, combining hand-drawn environments with detailed, 3D character models.
To save the day, the Blue Bomber must battle Robot Masters and take their powerful weapons for himself, which now changes the hero’s appearance with new levels of detail. The innovative new Double Gear system lets you boost Mega Man's speed and power for a new twist on the satisfying gameplay the series is known for.
A variety of difficulty modes makes this the perfect opportunity to experience Mega Man for the first time!"
At the moment its hard to say if this is the game's actual release date or a placeholder. Hopefully we won't have to wait too long for an official confirmation – E3 is just a couple weeks away!
