For 2014 the answer is probably yes. The hardware should be cheap to produce by now and the install base is big enough for software sales to flourish. After 2014 thing will be difficult. Nintendo hardware always drops in sales after the 3rd year and 2015 will see lower hardware and software sales. Therefore we might see the successor to the 3DS in late 2015. The 3DS launched in early 2011, so that'll be almost 5 years on the market, a normal life span for a gaming console.
The problem here is the Wii U will be pretty much dead by late 2015 and Nintendo can't afford low handheld sales and a dead home console business at the same time - that would kill their business. When the Gamecube struggled in 2004 they had two successful handheld platforms (the DS was their "third pillar") so they'll need some sort of new hardware in late 2015 (maybe the QoL platform but that one's a big gamble).
My prediction:
2014 - kept alive by 3DS
2015 - new handheld + QoL platform; Wii U getting only token support
2016 - new home console
