a couple of things come to mind, though firmware won't cut it for this one. in the future an 'eye detection' ability that would turn off the lcd when it comes close to your body - i've noticed that on the x100s, xe's and pros, the camera comes back to life much quicker than when on sleep settings.
as for firmware, add the tcl to the conversion lens setting. the wide works fine (actually really well) for the wclx100, so why not add the tclx100 so we can get a 42mm (wish) view.
make it possible to change film modes when auto is turned on.
as for things in the box - a lens hood should be standard included pieces. (dropped my x100s from about 66 inches onto concrete - thanks guy who wasn't paying attention - and it survived without a crack or scratch thanks to the now pancaked hood.
something better than the shoulder strap currently included.
