If you do, you are crazy.
I was listening to the latest 8-4 Play podcast, and near the end after discussing the Nintendo Direct that announced a bunch of 3DS stuff, they started talking about what Nintendo has left to reveal at E3, and one or more of them thought it was possible they might at least reveal a logo for the next Zelda. That is fucking insane that anyone would think that's even remotely possible. Skyward Sword came out like 18 months ago, you crazy fucks.
Nintendo already has one dev team making the upcoming 3DS title, and that does seem to pull resources/focus away from making a console Zelda. It's noticeable, when you look at how quickly they made console Zeldas during the era of letting Flagship handle portable Zelda development: Ocarina of Time, Majora's Mask, and Wind Waker came out in the span of 4 years (1998-2002). Conversely, once taking back handheld Zelda development, you had 5 years pass between Twilight Princess and Skyward Sword, and I'm willing to bet that working on Phantom Hourglass and Spirit Tracks (both released within that 5-year span) are the reason there was no Majora's Mask-style interlude after Twilight Princess.
If they had a console Zelda game coming soon, they sure as fuck wouldn't be doing Wind Waker HD. That game's reason for existence is pretty much to pander to Zelda fans who would otherwise be disappointed that Nintendo doesn't have a Zelda anywhere near WiiU launch because they were still working on Skyward Sword so late into the Wii's life cycle. Wind Waker HD doesn't even come out until later this year (assuming no delays), so there's no fucking way they're going to undercut their own HD rerelease by going "Yo dawg, fuck that HD remake, here's a logo or teaser trailer for you guys to lose your damn minds over".
Maybe Miyamoto will offhandedly acknowledge in some interview that they are working on a new console Zelda (because they obviously are, though it would be early still), in the same way that he casually acknowledged Skyward Sword and Pikmin 3 years before they were officially shown in a press conference. But there isn't a chance in hell that any Zelda will get mentioned in this year's E3 press conference aside from the new 3DS game and Wind Waker HD.
