To PMDG developers: what hardware is going to be supported with the 737NGX?

Hi,I was wondering if the developmentgroup of PMDG already has an idea as to what DYI cockpit building hardware is going to be supported with the 737NGX concerning FMC/CDU, FCP, EFIS etc...Also I was curious to know if PMDG is going to supply a SDK.Reason of asking is obvious :( Is Engravity still supported with their 737 FMC (intended for the current 737NG), CP Flight, OpenCockpit systems, or....? I'm interested in buyng a CDU, but am not happy buying, let's say, a Engravity CDU and then find out it won't work anymore with the 737NGX.
