I know it's frustrating to wait but Apple has been doing things this way for decades, effectively artificially spreading out hardware releases to maximise hype even though the internals are mostly the same.
One thing I'd say though is if you're planning on buying a Max powered Mac Studio then think long and hard about instead buying a MacBook Pro with a Max chip instead. I bought an M1 Ultra Mac Studio and suffered real buyers regret after a while and am now upgrading to a MacBook Pro with M3 Max. For as long as I can remember, I've always had a big powerful desktop machine. First it was PCs then Mac Pro then Hackintosh then Mac Pro again. The whole time, I'd often have a low power laptop for on the go. So that's what I was going for.
When I got my Mac Studio, I was absolutely blown away by the power. Apple Silicon was such a huge leap in performance. But then I came to realise that the Ultra may have been overkill for my needs and a Max would have been a huge leap in performance on its own. With that came the realisation that I could have had all that power while being able to be portable if I had just gone with a MacBook Pro instead. Being tethered to a desk was something I was always willing to live with when the performance was leaps and bounds over what you could get in a laptop. A decade ago, there wasn't even a comparison. But things are different now. Hence, I've decided to bite the bullet and switch to a MacBook Pro. It's obviously more expensive, especially as I've decided to upgrade the SSD over what my Studio has. I'll be using it as a desktop for 95% of the time. I've got a thunderbolt dock and an under-desk laptop mount ready to go. Being able to take my full normal work computer with me out of the office 5% of the time is just something that I've come to realise I really *really* want.
I had similar frustrations when the M1 Pro/Max MacBook Pros came out because I'd been chomping at the bit to upgrade to an Apple Silicon machine but felt I needed to wait for a suitable desktop machine. I was wrong though and should have just got an M1 Max MacBook Pro when they were released. It took me a lot of money to realise that (at least it's a business expense) so I thought I'd share my experience here in case it helps someone else come to the same realisation without having to spend the money to learn!
