So then, it's not disrespectful at all towards loyal customers (like said up top). It sounds like AT5 has a whole new IR engine, so here's to hoping that the cabinets we bought in AT4 will be upgraded to the AT5 versions, which are apparently redone.

Paging @ Peter - IK if you can provide further clarification. Going through the different version lists, I notice a *lot* of overlap between what I've already got and what's offered in the "Amplitube 5" edition.
