Oh, quite true. And yet a simple Google search pulls up photos and video that strongly indicate that the 12.2 size is being seriously investigated, even if it never comes to market. Consider also the size of a Surface Pro 3 and it feels more like Samsung either was ahead of the curve or caused someone to ask, "why not 12.2?".
While I would also never buy Apple (my wife has an iPad mini and it feels so clumsy as it "protects" the user), my hope is that Samsung decides to keep the 12.2 form factor alive and improving the line.
