Zelda may have been sticking with the same basic formula, but it has always added quite a bit to each game to shake things up. Ocorina brought the old style into a 3D world, Majora's Mask added in the various mask transformations and abilities, Wind Waker had it's expansive world and sailing Ideas, Twilight Princess added in the Wolf Form, Sword Tricks, as well as improved Horse based combat, and I can't comment on Skyward Sword as I've not played it.

This isn't getting into the handhelds of Zelda either.

Not to mention Mario games have had a huge variety of varience over the years as well, I don't think I've ever scene a company do so much with a single IP as Nintendo does with Mario.

So I really don't get where you, or people in general, get the Idea these two IP's are just a bunch of recycled Mechanics. (That said, I don't think I've enjoyed a single player Mario game since the N64 days. )

Also quite a few non Mario and Zelda Titles announced, such as Bayonetta 2 getting a date, as well as Xenoblade Chronicals X getting a date and some real information, (Though that is all next year), and the long list of Indies revealed I posted, many of which do include games from indie developers.

They led with their big guns, and gave us a lot more for those looking for something other then their main IP's. And since they did name quite a few games coming out this year they announced, and not just the EShop list (All of which is suppose to be this year).

Not saying that you should be hyped, just pointing out your points of 'no third party or indie support', '2015 heavy', and 'just recycled mechanics' are all kind of silly things.
