Nintendo can do nothing to gain more 3rd party western support until their console becomes viable with a large install base. If the 3ds could have received western ports, it would have. Same thing with the Wii. Switch can receive those ports because it is the same development environment as other consoles, and from everything we've heard, it is actually the easiest of the 3 to make games for and ports using popular engines can be brought to the console in around a week.
Now Nintendo's goal the next 12 months should be to surpass wii u's Ltd Sales, going into E3 2018 with that sort of momentum, can attract lingering 3rd parties to bring their ports over and be willing to talk about exclusive deals.
Currently we are probably going into this E3 with a 1st party focus and likely more Ubisoft titles, probably cod as well.
