Certainly makes you think twice when it is close to what you know, but has something minor missing, like the BT KOs. Those mini jets you are thinking of, have the jets showing in window on the front, so at least it isn't that. Like this one:

But looking up on ebay us, I did see the regular Skywarp reissue, with the green 'commemorative' bit, plus a different group of 'other figures' inside the flap. Like this one:

It also had me thinking that maybe the one you found could be a UK release, and maybe their's are slightly different (as with many of their TFs packaging over the years).

I had a look on ebay UK, specifically for the other figures that were inside the flap of the Skywarp you found, and came up with a few with similar packaging variations to the Skywarp, all listing the same other five available figures.

And the other one being Anniversary Optimus.

I think if you aren't worried about packaging, the toys *should* be the same. But maybe ask the dealer. But that dealer is one who lists everything as 'last stock' no matter how many he lists, and has listed KOs in the past.
