It is extremely unlikely that we will see any products next week utilizing the M4 Max or M4 Ultra SoCs. It is crystal clear that Apple Engineering (both hardware and software) doesn't have the bandwidth to launch all four variants at the same time or in quick succession.
Furthermore there are usually some hints when a new CPU is incoming: Geekbench results with mysterious device IDs, references in beta versions of the operating system, etc. There are no such teasers for the Max and Ultra variants of the M4 silicon at this point.
Other tech media sites (Bloomberg is one) have speculated that the M4 MacBook Air is coming in Q1 2025 with the Mac Studio to follow later. A good bet would be for the Mac Studio with M4 Max SoC to be announced at WWDC 2025 in June.
Another thing not to expect would be any drastic price cuts. It's not like TSMC's latest and greatest node is some sort of bargain offering. Tech media has repeatedly reported wafer price increases. Apple will be pass this along to customers, it's not like they are going to take a major hit to gross margins.
I also doubt the unveiling of a new Apple TV next week. I'm not sure what new silicon would bring to the table. Maybe a couple of minor features but certainly nothing major like a resolution increase. 8K video for consumer devices still isn't here yet even though NHK Japan has been doing terrestrial broadcasts for several years. An Apple TV that does 8K video probably won't come until the FCC migrates to 8K terrestrial broadcasts for US television stations.
