Even in other basins it is noteworthy, and it may possibly mean that the same could occur in the Atlantic eventually too. If the water is warmer at higher latitudes, and cyclones can maintain their intensity a bit longer, it would make sense that the point of its maximum intensity could inch more northward (in our hemisphere). Although, it is important to note that we are talking about the point at which the storm is at its strongest. While on average the exact location of the maximum intensity may not be migrating further poleward in the Atlantic as of yet, it could still mean that storms are coming to higher latitudes with more intensity than they have been previously. A storm may have its peak intensity at about the same place as other storms in the deep tropics, but it could remain rather intense, more so than other storms on average in the past, when it reaches higher latitudes. Just to throw out an example, which is a bad one because Sandy was not a tropical cyclone at landfall, but Sandy peaked in intensity at about 20N, just before it hit Cuba. Look what it did to areas around or above 40N. If that had been purely tropical and therefore applicable to what we are talking about, you could see that it would not have mattered if the point at which it became its strongest was a little further north or not. (I'm not sure if Sandy peaked above or below others storms latitude on average.) Of course the other thing is that Sandy ran into land in Cuba. That may be another reason why the Atlantic may not see the latitude rise too much. Shallower water and land interaction would be my guesses as to why there might be little to no noticeable change in the Atlantic in comparison to other basins that have deeper waters with more room to spare because of less land in the way. Just a guess.
