I don't see any indication that the A4 Deluxe amps, other than the British Collection, are anything other than the old existing A3 models. They are not re-worked versions expressly for A4. I do, however, agree that if the content from A3 has been axed down to what I see that a new customer is going to be putting more money on the table for the same amps we got in A3. I really think the value point for buying A4 is not near as strong as it was for A3, as far as content. This is going to hurt sales I'm sure.
I'm still waiting for the upgrade to get ALL the 29 speakers we were supposed to get. IK said they would fix that. Maybe they will fix this as well. Time will tell. Meanwhile, I wait for the other shoe to drop which will be ALL A3 amps have been re-worked for Hyper-Realistic performance and you will have to re-purchase all amps in the Custom Shop to benefit from A4! I hope it doesn't go that way but I sure suspect something along those lines.
