I am a Wii U owner and a nintendo loyaliest but even I can distinguish between short term gratification vs long term gratification.
I was one of the people who said hell they should cancel the Wii U version. NX needs everything up it's sleeve to bolt out of the gates.
What good will releasing Zelda U on a dead console do fo the future of Nintendo and me enjoying more of their games? If NX tanks NIntendo are pretty much done dusted adios.
well not everybody is that likely to throw money away.
Even if 50% of the nintendo fans are ok with the delay, 50% are not and that will hurt nintendo.
