Newsbrief: The Marmalade game development toolkit has expanded with the addition of a new 2D Kit, in beta, and a 3D Kit. The two packages do what you'd expect: help develop either 2D or 3D games, respectively.
The 2D Kit contains an entirely new 2D editor interface that allows for drag-and-drop scene layout. 3D Kit, meanwhile, is designed to improve Marmalade's integration with industry-standard 3D packages like Maya and 3ds Max, and FBX format files.
There's more info at the company's blog, and further on from that post, plenty of much more detailed info at its developer portal for both tools -- linked from that post.
