Both MacVIM and Komodo Edit have been around for years, and haven't really changed much while Allan has been working on TextMate 2, so I can't see how that's relevant.
MacVim has seen a huge number of changes in the 2+ years that TextMate has been under development: not least Leopard support, Vim 7.2 integration, and a ton of interface and speed improvements. They're on Snapshot 45 right now...
