You may suggest all you want, just like the rest of us, but that does not actually make it so - or give us any more clarity on "platform" vs "calypso" items. Something having dropped on another planet does not make it non-calypso item. I will give you "argonaut skull" as an example if you can't think of any others yourself.
Logic tells me so
There are only a handful of possible scenario's
Either the pre pp loot codes are owned by MA (not sold to FPC with Calypso ) and used as generic shared platform loot to new starter pp's untill their roll out their own unique non platform loot. (The one i believe it is)
or
The item codes were bought by FPC now SDS and they (SDS) are leasing out the item codes to other pp's thereby destroying any chance of Calypso remaining unique in a growing universe. (Highly unlikely they are doing this)
or
All PP's designs automatically become the property of MA or MA leases them and then distributes the loot codes as they like (unlikely)
or
Item codes are illegally being used on other PP's (Very unlikely)
or
MA cocked up yet the loot still keeps dropping ( Possible on the short term, but not likely on the long terms as it is now. So unlikely)
The argo skull as you mentioned forms part of the loot designed by ma for MA mob (Now Calypso mob). Im sure new pp's can assign platform loot to their mob as they might before they get their own unique stuff. The Drummies were most likely assigned to drop MA's generic package loot for Argo. Of course afterwards MA realised Argo sculls is mob specific and soi cannot be platform loot like all the rest. So any loot like skulls, claws etc from ex MA mob or now Calypso mob is unlikely to form part of the platform loot.
But you are correct, we do not know for sure whats going on until they tell us. My guess is they wont tell us, but to me it definitely seems MA has secured generic platform loot which as it happens, turns out to be the loot from their own creation.....Calypso. So now we just have to wait and see if Calypso (SDS) is going to remain be the "Ikea" of the Universe or if they going to get with it like the other PP's and get some new stuff unique to Calypso (SDS) soon
Sry if someone takes this as a attack on whoever, because it is not lol. I just like to debate and this is quite a interesting move if true
