I had recently purchased a 3DSXL prior to this new unit being announced. I don't think the minimal upgrades are enough to make me want to upgrade.
Honestly, the only reason why I even buy Nintendo products anymore is because their games only exist on the hardware they produce. Their software, hardware, and services, are very outdated and poorly designed. I really wish Nintendo would get out of the hardware business and make their games available on other platforms that do literally everything better.
As it is right now, Nintendo has to try to convince gamers that a $300 console that can only play Nintendo games, with hardware and software that is vastly weaker than the competition, is actually a worthwhile investment. They also have to convince existing 3DS owners that the upgrade is worth it. But I think gamers are starting to wonder why they should spend $300 on a crappy console or $200 on a weak handheld, one of which is filled with shovel ware, while the other has received no support at all, when they can just as easy spend $50-$100 more and get a console that has fantastic first-party and third-party support, with the only drawback being the lack of Nintendo support.
i hope that within the next 5-10 years, Nintendo will stop trying to ice skate up hill and get out of the hardware business altogether and start developing their games for the Sony and Microsoft platforms, and maybe PC. The idea of not having to worry about Nintendo's ridiculous hardware gimmicks alone would be worth it to me. I know people might bring up Sega and say "Well, look what happened to them after they quit hardware!". The difference is, Sega sucks ass and sucked ass for years before they even left hardware behind, and, well... Nintendo doesn't suck ass.
