Rivers seem completely flat from the screenshot, which in the case, flowing water wouldn't even make sense. Rivers in real life flow because of gravity (Durr). I could personally care less if the water flows or not. I'm just happy the terrain generation is going to be a ton better.
If only that finite water mod became vanilla. Then we'd have real finite water (except ocean water), and rivers could actually work even if the source lake is 1 km away from the delta or mouth of the river and 1 meter higher than the source.
Judging by the map he put up on Twitter as well as the screenshots, it's completely flat, and rivers don't have sources. They just sort of meander through continents into other oceans. For the interest of gameplay, it's still cool, and honestly, real-life physics don't apply to Minecraft anyways. I mean, you can have floating blocks, you cut trees from the bottom up without them falling, and you can build ridiculous structures that would collapse in the real world. Honestly, who gives a **** about realism in the end?
