I sure hope so. TextMate bundles seem the logical choice since Rubyists seem to love TM, and I do, too. That said, I'd switch IDEs if the library was good enough. I actively acknowledge I am taking advantage of Xcode's CodeSense when it comes to some of Apple's asininely long enums (UITableViewCellAccessoryDisclosureIndicator for instance).
I wonder if people are working on autocomplete packages for different IDEs/editors to help make RubyMotion smoother with those long method names (didn't see much googling it). IMO in combination with this, autocompletion would make RubyMotion a tremendously compelling option for iOS development.
