The default deployment settings will indeed generate a pretty big application, but it is possible to trim out unnecessary stuff (such as the standard library or extensions). Also, we are hopefully dropping i386 support in 0.10, therefore the MacRuby binaries will be 2 times smaller.

From one presumably in the know, that would lend (to a suspicious individual like myself) credence to the theory that.. a future version of the OS will definitely be 64-bit by default. 2 times smaller? I wish I had the math chops to compute/debate that, but it seems like an even more substantial gain than dropping PPC code in SnowLeo did(plus binary/compression optimizations).

A bright future, thanks for all your dedication and hard work!
