ASSUMING this is all real, my thoughts:
Good:
-I adore the grass snake king evo thing.
-Hydra is amazing.
-Centipede is amazing.
-New fossils is awesome.
-Fighting trio is unique.
-Bug/Steel event legendary is the single greatest thing gamefreak has ever done ever. If they make it look at least decently unretarded, it is better than Arceus. Nothing you can say can refute this.
-Lots of new Ice, Dragon, Poison and Steels.
Bad:
-Fire/Fighting starter has officially caused me to lose any and all respect I ever had for gamefreak's ability to create decent starters.
-Wotter final evo is just bizarre.
-Mamanbo is a complete waste of space if it doesn't evolve from Luvdisc. What's next, they'll make an Ice/Psychic with decent stats, a feminine dancer appearance and a relative rarity and make it unrelated to Jynx? Same thing applies to the dancing cactus if there's nothing setting it apart from being a Cacturne evo, and Tabunne if it's not a Miltank prevo.
-No new evos. What the hell. Half of the things I really truly wanted to see from this generation were upgrades to old pokemon. For christ's sake, you make a Duskclops/Electabuzz/Magmar/Piloswine evo in gen 4 and then ignore stuff like Jynx/Absol/Luvdisc/Cacturne/Farfetch'd/Tauros.
-What the hell is with the alternate forms. Psychic Hihidaruma is just...dumb.
Other:
-Pokemon #38: Machop with a 2x4. Greatest concept ever.
-Glad to see Gigaiasu and Gearu are 3-stages. I dunno why, I just like 3-stage lines.
-In general they're reusing a lot of concepts. Frog is the new Quagsire, Gigaiasu the new Golem, Koromori the new Zubat, Girderman the new Machamp, Kurumiru/Toxipede the new Caterpie/Weedle. On one hand new versions of old concepts is nice. On the other, they better not be running out of pokemon.
-Are you seriously trying to tell me Kibago evolves into Ononokusu? What? What.
-Elvis Yannapu VS MetalEtemon. Seriously.
-Why is the cat a 2-stage and the dog a 3-stage?
-Why are the pidgeons so far down?
-I'm willing to bet a small monetary amount that each and every cool Pokemon will have a person english name. *coughdrifblimcough*
