From what I can tell this is real, but what in capacity remains to be clear until around when E3 was scheduled. I hope we either get a collection of the 3D Zelda's with a separate 2D collection or the entire series. I would ideally want a collection of all titles, but I feel like Nintendo would not pack that much into one SKU. The hardest title will be Skyward Sword so part of me wonders will that title get its own release then we get a collection with OoT 3D, MM 3D, TP HD, and WW HD.
It really depends on how they'll handle the Mario games first, really. Assuming it's a collection with everything sans 3D World, which would be it's own SKU, then we could hope for OoT/MM/WW/TP in a collection and Skyward Sword as a separate release (or maybe even included in the collection, which kinda feels overkill, but who knows?). If they were to release them in pairs, then it would be OoT/MM, followed by WW/TP and SS released either by itself, or bundled with those last two.
In any case if it were to happen, I'd expect OoT and MM to be the 3DS ones remastered (maybe go back and fix MM3D while they're at it) and WW/TP to be pretty much straight ports, only removing the Miiverse stuff from the original Wii U versions. Skyward Sword would likely get the TPHD-style remaster as well, with mostly QoL features and adjustments to make the game flow better for those who didn't like it originally (I hope they keep the Silent Realms untouched though).
