People were asking for J41 fixes right after release, not after 2-3 years (e.g. the triangular polygon bug). That time we thought the NGX development causes the delay of the SP2, so I think there's nothing unfair in asking for it again after the NGX's release.But guys, do not hope too much in the upcoming SP; I had opened a support ticket back in July, and listed more than eighty issues with the aircraft's systems for the PMDG developers. They responded that because the J41 is only a low-cost model, it's "highly unlikely" that they're going to fix any of those. Based on their answer, I don't think PMDG had ever really planned to release a new SP; simply they won't earn enough profit from doing so.They had to decide which is the better: to invest some time and money in developing or to leave behind some unhappy customers with their complaints. Jetstream owners, I think there're too few of us! :-)I wish I was wrong... anyway, Christmas is coming, maybe they'll suprise us! :-)Márton Takács
