BMW has registered European trademarks for a number of terms including "Urbanic," "Compactive," "Compactive Tourer," "i" 1 through 9 and "E" 1 through 9. Bimmerfile speculates that "Compactive" and "Compactive Tourer" belong to the GT versions of the F20 1 and F30 3 series models; "E" refers to the electric vehicles being developed; and that "i" and "Urbanic" refer to the iSetta. However, nobody really knows so we will have to wait to for an official statement to find out.
