at least if you buy the sequel and it will be mergeabel (highly possible IMO ) with CoD, one will get the engine and GUI improvements. If not, we have to see how they will support the CoD alone . And a BoM alone also , if it will work alone at all.
i cant imagine they want have the same like with PF , one X.XX and one X.XXm patch. perhaps if you will buy BoM, the CoD stuff will be included, so this sequel will be a restart of the series
