Those against Fusion have to realize, it all boils down to manpower and overall software support for Ninty.
IMO the NX is also about mobile tech catching up, bridging the console gap with the transition to HD. Now, some of us suspect Nintendo is more than satisfied with the Wii U level of performance, if you ask ShiggIwata they'd probably say the full potential hasn't been realized. Remember, with the GCN's disappointing sales, Ninty was so upset they basically remixed the HW for Wii, rather than make the HD leap. Have a feeling with U's awful sales, a similar thing will happen, and just like the OP points out the NX home console should be a modest jump.
Nintendo will continue building its HD development, which will lead to a rebranding and repackaging of U (NX home version). Easy to understand why Nintendo doesn't want to put Zelda on a "dead" console, just like TP for GCN, so the goal IMO is now cross-gen to help the launch of new HW and appease U owners. I am personally hoping for NX home to be without disc, no power brick and be just as portable as the HH... hoping Ninty will go for elegance and appealing design.
NX should be a modest evolution from Wii U, games built with the highest quality assets (home or deluxe vers.) then get scaled down in res and other settings for the HH. This move is more than necessary for Ninty as they continue alienating themselves from the main market. If you people that wanted a XB1 level power console from Ninty and compete with MSony again, they had their chance in 2012 with the 1 yr head start and blew it, so if there was any doubt about the power issue, its dead at this point, don't even dream about "stronger than ps4". Instead focus on the ultimate Nintendo system, where you get to choose your experience (hh, home, tablet etc). There may still be platform exclusives, to encourage sales (i would be against this) but NX should mainly be cross plat, & a great thing t Ninty fans should celebrate.
