I'm in full support of OoX coming to the 3DS as they're two of my favorite handheld games ever and my favorite handheld Zeldas more importantly, if we don't count ALttPGBA. Like most others have stated already, I don't think a petition is necessary at this time. Nintendo has Zelda 3DS, Zelda Wii U, and more likely than not, the theoretical MM3D on their plate to deal with. Yet another petition might cause the company to snap under pressure...or something.
Now about that Link cable dealio. I myself am a professional link cable user due to err...nefarious manners of using link cables. Whatever you can do with the link cables in OoX can be done with the passwords you get ingame. Or, alternatively, you can basically unlock everything using this nifty program called ZeldaPasswords, the link for which I won't provide (iirc it is on ZD main site, could be wrong). Once again, link cables aren't necessary in the slightest of ways, they're simply there as a substitute for using the Passwords feature...a quicker substitute, might I add, but still unnecessary.
