I know lots of people are kind of hating the idea that the announcement will be sinnoh remakes, but secretly I'm actually hoping for that!
Yes let's remake the remakes! Wait we already did that...Everything seems to be hinting towards either Diamond/Pearl Remakes, or FireRed/LeafGreen Remakes. It could be either one of them. I don't really expect Pokemon Stars/Eclipse.
I was personally REALLY pulling for Diamond/Pearl remakes, but I think there is still hope for those yet. I think maybe just a few more years. Ultra Sun and Ultra Moon look interesting, a lot of unanswered questions about how the storyline will be. All in all, I think we should give it a chance, might be really cool!
I hear a lot of people complaining that Ultra SuMo didn't come out on the Switch. I guess I see where that argument comes from, but I personally think they need to keep main line Pokémon games on the 3DS line. Smart move by Nintendo business-wise to keep two consoles alive like this, I think.
