Series Producer Eiji Aonuma has said that this new installment in The Legend of Zelda franchise will be a clean break from the conventions of previous games, removing boundaries that forced players to follow a set path and introducing new gameplay that has not been experienced in previous games in the series

 Also this is from ofical E3 Nintedo site, it seems that game will have Sheikah focus

This picture also, pay attention on book.

Bouth thigs are very exciting. :)

So, that's probably when the genre-bending will be. Link with the ability to transform into a girl, pretty much the same way as Zelda going into Sheik. Maybe. That's a theory I like. Also, E3 is just Zelda then? XD.

Sheikah yessssssss *-* given the pattern on Link's cloth during E3 2014, the Sheikah book in the November Direct aswell as the latest artwork I think it's VERY likely that the new Link and Zelda will be members of the Sheikah tribe...
Also those symbols around the eye makes me think that the game will have a huge focus on tecnology...

Added latest artwork in OP.

It would be cool if the Sheikah were featured some more, they've always been something legendary. I agree there's been plenty of hints in trailers and the artwork.

That would be freakin awesome. I've wanted the Zelda games to expand on the Sheikah for a long time.

That's exactly what I thought just by reading OP's title thread!

I'd love that. And that the transformation will give Link different abilities. Ninja-like abilities, like Sheik. I'm sold on that idea XD.

Definatly seems like Link will is part of Sheikah tribe.

I expecting GameXplain will make 15 min video about that new logo. :)

Can you imagine that, after all the debate and discussion about the book, it turns out that the final battle ends up like this (0:19):
