Karnak, I believe you are mistaken, there has been no official user (in-game) poll since. I just went looking again and found no poll, at least which had its results published, as being more-recent. If I recall correctly the first post/mention regarding the 410 entering development from HiTech or HTCs has the answer, but from my (s!@#y) memory it is because it scored greater than 40% against the B-29 in the final round of the poll I quoted earlier.
