Not to be too picky, and I know the chart is meant at a very basic level, but I believe I recall that while you cannot play within the DI 1 play sets on DI 2.0, that they will have some functionality in that when you place the DI 1 playsets on the base in DI 2.0, it will unlock all the items from the playsets in the DI 2.0 toybox. Is that information accurate?
