When you are finally successful, brace yourself for the other number: the price. I strongly believe iMac "bigger" will be resurrected, branded PRO and priced about the same as last iMac 27" PRO.
Any concept that the old iMac 27" pricing will also resurrect can't seem to fly. If the iMac 27" monitor alone (ASD) is priced at about $2K with stand option, adding a whole Mac + keyboard + mouse to it seems the price must considerably rise above $2K.
Brand it PRO (for PROfit) and my guess is "starting at..." about 2X what we remember as iMac 27" "starting at...". Those specs will probably be too weak, so upgrading RAM and SSD a tier or two should get into Mac Studio + ASD + keyboard + mouse territory.
If your hope is old pricing, I'll hope right with you.... but I just can't imagine $2K ASD and $2K (same monitor) iMac + Keyboard + Mouse. So for former iMac pricing, Apple would have to heavily cut ASD pricing and I don't see any reason for them to do that now that it is established at former "whole iMac 27" pricing.
