It's difficult to say because it's hard to guess exactly what New Japan's plans are. During the G1 Special, it was announced that New Japan would return to the states in 2018, though exactly when in 2018 is anybody's guess. If their plan is to try to compete with WWE, then my guess is that they're not going to rush into anything anytime soon like TNA tried to do after Hogan & friends showed up. If the plan is to compete with WWE someday, then taking it slow is the right decision because it's not going to be easy by any stretch; New Japan isn't remotely as well known in America, it generates less than 5% of the revenue WWE brings in and they'd have to land a TV deal on a real network or, at least, really build up the audience they have on AXS TV, etc. and it's all going to take years to do.
However, as of right now, Kenny Omega looks to be a clear choice to represent the US market. Omega is easily the most talked about Caucasian wrestler in the world who isn't wrestling in WWE and really has been since the beginning of the year, he became of the first IWGP United States Heavyweight Champion over the weekend which means he'll be spending some time in the states defending the title working with companies like ROH.
