This rumor is based on nothing. Nintendo never leaked the NX name, no one ever made a mention of it, but now that they say it officialy, all of sudden we are supposed to believe that some ppl know about LoZU and XCX coming to the system. These rumors are made by ppl who have time to waste and are looking for attention.
Also, Iwata said they are hoping to share more info about NX next year. So best case scenario, they show off NX at E3 2016 and it launches for Fall2016. What is most likely going to happen tho imo, they briefly showoff NX at E3 2016, with only few concepts and ideas about what the gimmick will be (cause lets face it, it will have a gimick), they will try to sell us the idea of that gimick being the futur of gaming, no games showed, and the launch will be Fall 2017.
Either way, XCX is coming out next month in Japan, ZeldaU is scheduled for this Fall. They won't delay these games for more than a year (perhaps even two) to make the launch of NX. That's not saying they won't do a Sony and release a deffinitive edition once NX launchs, but Nintendo has no history of doing so, so there is no reason to believe for sure it will happen. And they would be no way these ''deffinitive editions'' be planned before the original games are finished, meaning that there is no way that info could have leaked to these rumor spreaders.
As for the poll, I think it will be backward compatible. I hope it will be but that would mean that the gamepad would have to work on NX. I think it will be because theyve always done it, but with competitors droping the idea in favor of their virtual catalogue, and with the obvious focus on the Virtual Consol for the futur, I would sadly not be surprised if it was'nt.
