thomas and friends mini series

So with the TMNT 9-Pack now released...does anyone know if they're will be a 4-Pack released? The previous picture of the 4 pack has the same 4 trains from the 9-pack. It's listed on the wikia page as product code DWG69. Any thoughts?

That's what I thought, but it looks like 4 pack either got scrapped or they will just sell the 4 of the engines as 4 pack later on.

By the way I was able to grab new 3 Pack with Steel James at WM today.
That completes my collection with the soon arriving TMNT and recently arrived Slime 20 pack and soon to arrive 7 pack, except the $100 playset.. :/
