Gurman writes that Apple’s design team has created prototypes of the mouse in recent months with an eye toward creating “something that better fits the modern era.” He doesn’t get into any specifics — the group still hasn’t settled on a design — except to say that the mouse will address the charging port location and other “longstanding complaints.

Apple's redesigned Magic Mouse could "still take months or years" of development after the design for the accessory is finalised.
