@Pietro_Mele - Your initial post (before your edit) suggested otherwise.
To my understanding, pre-orders are only made available for upcoming products.
It’d make no sense for Framework to undermine their own upcoming products by announcing even newer ones in the meantime before delivering the further.
And once a product has become available and all pre-orders have been served, the possibility of pre-ordering said product will cease, like for the current Intel 13th-gen- and soon for the AMD based Framework Laptop 13, as said products can be shipped shortly after the order has been placed.
To put it in a nutshell, I don’t see a use case for your suggestion regarding new CPUs.
Regarding periphals: you are already able to change your order a last time when receiving a message from Framework about your pre-order being made ready for shipment and can add anything available in that area in the marketplace at said time.
No, because, as you have already been told further up this thread, FW would not be releasing a product that had an optional change like that before they had finished shipping all the preorders for the one you originally ordered.
Secondly, the preorder system (thus far) has only had back orders for about 3-4 months, so trying to order a product for 6 months hence would not be possible.
