Guy,
Closed interfaces mean that the maker is afraid of opening up to competition. Otherwise you have to best of breed in every area. The problem is usually that the closed systems vendors get boxed out since they cannot compete in all areas at once, especially for small companies, so their sales -curve is truncated when they are eclipsed in any of the dimensions they attempt to control.

lets see if the camera will work as good as it looks to me at the moment.
in that case i am pretty confident that someone will make soon adapters for it. it should be a nice little business,- so far it looks to me there is no other camera available with similar specs and so many colleagues will want to use it. for me it will be a personal honor if the things go that way.
as i believe and if we like it or not, the mf back makers are in a very strong competition between themselves, so no one will want to feed the cash box of the other brand, not directly and not indirectly. you cant compare here a manufactory as sinar with alpa or cambo, which dont sell backs, so their main interest is to sell their camera to all brands. its a pity, but it has its logic.
the good news is that at least two brands work already with the arTec, sinar and leaf. ( certainly its not sinars fault that leaf decided to construct a new fixed mount for the afi, and not a removable adapter for the older leaf backs as sinar has done it with all its product line ).
in any case it should be a simple thing to make an adapter. ( although i am not 100% sure if i dont tell bs. here, because its still possible that the arTek hy mount brings the sensor closer to the back-lens as e.g. a h/ v-adapter could do ). its certainly nearly a wonder that sinar could make a rotatable mount and bring the sensor still close enough to the lens for the ultrawides.
but "locking out" someone is another thing for me as sinar is doing here. locking out means for me that it is impossible for a 3. party to get access to the mount,- as its done with the h3 or with the hy/afi ( for its complex electronic connections ). am not sure if there are patent rights on the mechanical hy connect ( as it was long time on the leica m mount ), but no one said such thing till now.
but, if we like it or not ( and i dont ), the manufactories always tried to "lock out" their competors or at least to make it difficult for them to eat the ready fruits, but to be fair here,- i think sinar has been the most opened manufactor, also in terms of the changeable mounts for its backs.
i always found this a fair and important feature and i used it a lot,- using my backs on gottschalt,contax,hasselblad and sinar m mounts in the last 3 years.
