The Gaming X Trio is being phased out, and retailers here in the Netherlands have started canceling pre-orders. That's not the entire story though, as the Gaming X TRIO is to simply be replaced by the Gaming Z Trio.

The question occurred because Alternate (huge etailer) here in the Netherlands was referenced in Reddit, unfulfilled pre-orders for the MSI RTX 3080 Gaming X Trio would be canceled. That information was relayed to the pre-order customers. MSI has confirmed this. According to MSI, there are no differences between the 3080 X and Z Trio in terms of clock rates (GPU and RAM) - the only difference would be found in the backplate (change from graphene to metal). 

We reviewed the Gaming X TRIO at the time of release, and it is an excellent product.
