A few interesting points from the leaks (nothing story-related):
Leech Life is now a TM and its power has been increased to 80 (stronger than Drain Punch and Giga Drain!)
Apricorn balls are available again (Moon balls mentioned specifically)
EXP Share works the same way as in gen6 so no changes there. You also get it early on in the game.
Some old pokemon have their abilities changed (like often happens with a new generation) Gigalith -> Sand Stream, Vanillish -> Snow Warning, some talk about Gengar losing levitate has been around but not confirmed
Also related is that for some reason the whole competitive community is whining about some base stat reveals as if the new pokemon were expected all to be meta-changingly powerful.
This is a spot on the Pacific Crest Trail in Southern California, in the mountains near the Los Angeles Basin. Generally dry, close to the Mojave Desert, rocky, with some water flowing because it’s still spring.
The coven witch Maghda has been slain and Deckard Cain has been avenged, but there is still work to be done. The prime evils loom on the horizon, and the Black Soulstone must be used to defeat them. Now we turn to the spirit of a long-dead wizard for guidance.
Unlike most other Pokemon, when Flygon finally gets to its fully evolved form, it becomes more passive and defensive, as its predecessors actually are quite aggressive. Flygon will only live in deserts, where it will use its tail to whip up sandstorms and immerse itself in sand to defend itself. With its new covering for its eyes, even the most intense sand streams have no chance of impeding its vision. This is a rather rare and powerful Pokemon that would be difficult to catch.
…a species of Cyprinid fish that is native to North America, where it is known to occur naturally in Mississippi River Basin from southern Wisconsin and eastern Indiana to South Dakota and Wyoming and south to Louisiana.It has also been introduced in Arizona, Alabama, California, Colorado, Illinois, and several other states. Red shiners are typically found in a variety of aquatic habitats, including backwaters, creek mouths, streams containing sand and silt substrates, riffles, and pools. They are fairly tolerant of areas of high turbidity and siltation, but avoid high acidity. They are omnivorous in nature, feeding on both aquatic and terrestrial invertebrates, as well as algae. They are also sometimes known to feed on the eggs and larvae of other fish.
