I contacted the IGear. I was curious as to what does the indefinetly delayed means. I told them that I had pre-ordered a couple Nemesis black trailers from TFsource for my MP-01B's. I asked in the email what are my options and what gonna happen. Their response was that I should cancel my pre-order. So I am assuming since the Sharkticons are delayed as well it probably will have the same outcome. But they still image them on their website. There is still hope.

They are very friendly and have given me prompt replies.
Good luck
