To be clear, this in no way is anything like the DS revisions. Never did the DS add extra buttons, it did add a faster processor but there were no major game releases that required it.
With this "New" Nintendo 3DS and XL, we are seeing more controls and a faster processor that is making it a requirement for some pretty heavy hitting software so far. Xenoblade Chronicles is a pretty big game compared to some eShop download title.
I am really upset. I bought an OG 3DS and got screwed on price (Ambassador program was ok I guess), and then a 3DS XL which is now obsolete for these new titles. My Circle Pad Pro for my XL will not let it run Xenoblade, so people need to stop making that excuse. I am sure the added horsepower has something to do with it.
In the end, it is sad to see Nintendo go this route. They fucked up by not adding these controls that were necessary from the beginning, and the customer is supposed to pay to fix that blunder.
Fuck off Nintendo. The 3DS has been the shittiest you have been to your fans, with the price drop, awful launch library and games afterwards, and a 2014 that pales in comparison to 2013. I feel we are paying for Nintendo messing up.
