Yes. There are new, longer cutting plates for the CB that will work with the Sizzix/SU BigzXL dies.
CB Long Cutting Plates (B plates -- pair)
The BigzXL dies will fit through your CB, but the Sizzix XL cutting pads (what Sizzix calls cutting plates) needed for those dies are too wide. Provo Craft realized people were selling/not buying CBs and buying Big Shots/Big Kicks for the BigzXL dies and finally put out cutting plates that will fit through a CB. There are also some new CB items that require the longer accessories.
