I guess they will ship with swappable shells
Well, that's a rather cheeky reply on their part. But, I try not to presume given that for a long while they were selling different versions of the EZ IV and they each had different capabilities. Made me want to get one of the (somewhat absurdly named) EZ IV Lite Deluxe. Regardless, the amusing part to me is that when/if I do get their new version, instead of 50% of my time being loading GBI and 50% being loading a game, it'll be closer to 99% loading GBI*.
