That's...rather insulting to casual gamers. Consider that a lot of the people on these forums are casual before you make statements like that. And honestly, none of us know everything about Nintendo products. But we know the basics. If we didn't, we wouldn't even be gamers at all. Also, casuals are not the majority. They are small minority. They are easily outnumbered by hardcore gamers and even non-gamers (when they are present in the market, as they were with the Wii). If casuals were a majority, the non-Wii Nintendo systems wouldn't be selling so poorly.
The 3DS had a poor library when OoT3DS came out and Zelda has a larger reputation than it did when the original came out.
No. You are comparing series to each other. In Nintendo platforms, the selling order is usually the same with Mario and Pokemon dominating, Zelda in 3rd place, Donkey Kong and Metroid fighting for 4th and 5th, and Kirby in 6th. Some series are more popular than others and the name alone is going to sell the series. That's why Mario is going to keep outselling Zelda, no matter how critically acclaimed the games are. Likewise Zelda is going to outsell Donkey Kong, Metroid, and Kirby because it's a bigger name. You can compare the series success to each other, but trying to compare games from different series is inaccurate as a series' success will influence a game's success.
In the end, no matter how good or bad a Zelda game is...of course it's going to sell better than the less popular Nintendo series and unknown third party series.
No...it wouldn't. Just because someone just game as much as you do doesn't mean they're illiterate imbeciles. I could bring OoT3DS to my nephew...he's 7...and he'd be able to tell it's a remake. Why? Because it's on the box. And he's not even old enough to play it.
I'm a casual gamer, so yes, I would expect casuals (and especially hardcore gamers) to grasp such basic knowledge. Also, a large part of your argument relies on the consumer being a newcomer to the series. The majority of consumers are fans, and what Zelda fan doesn't know what Majora's Mask is? And if you're literate enough to play Zelda, you will easily realize from the commercials (and the fine print) that MM3DS is a remake. The name alone heavily implies it's a remake.
I'm curious...why do you expect it to do better than OOT3DS? You're main argument for it doing well in general not only defies all previous history with Zelda remakes, but is completely unfounded and relies on a completely stupid illiterate deaf market that apparently didn't exist until now.
