I actually own both a DSi XL and a 3DS XL and I bought them for Pokemon (yes I'm not ashamed to admit that I still play the franchise, it's still fun and a lot of the changes they've made over the years has made the game so much better). I grew up playing handhelds unlike a lot of our generation that had access to the original NES or the SNES growing up so I'm always going to support them because it's nostalgia for me (my first console was the PS1) and honestly some days I'd rather grab my handheld and play then turn on my PS4 or computer. The problem with taking games like Pokemon, Bravely Default, etc. and bringing them to the console is there is no call to do so. They sell extremely well on handhelds and gamers now-a-days are looking for flashy graphics and, as I mentioned above, more action based combat. Sprites and bad 3D modeling isn't going to cut it for a console game (and yes I realize Indie games do this all the time but Indie games aren't asking for $60 to purchase there game either). Most of the Turn-Based RPG generation moved to handhelds when it was apparent that they were going to get all the good RPG's. Honestly I can't even say that anymore because Steam is getting FFVI next week so you could even say the PC Master Race (yea I had to say it) are also getting all the good RPGs. Console based turn-based RPGs are a thing of the past sadly. We'll continue to see games like Mass Effect, Dragon Age, the Elder Scrolls series, and FFXIII/XV from now on when it comes to console based RPGs. It pains me to see it and pains me even more to know I contributed to the stagnation of one of my beloved genres of gaming. Thankfully RTS's evolved with the times and actually got better.
Mr. Happy brings up quite a few good points in that video about this multi-part decision for the game. Was going to post it earlier but never did get a chance to.
