I know this site already. Sometimes the quick glance value is not accurate until a valid serial number is entered. I don't have these machines so I cannot enter the serial number to get the answers.
I want to estimate how much I could lose if I buy M2 Pro or M2 Max now and trade-in when M3 Pro and M3 Max come out. Hope I don't need to explain further why I do this and that.
Thank you
Well.... it seems to me that if you are saying that you don't currently have access to machines with these particular specs or even access to their serial numbers, it is rather odd that you are asking others who might have machines with the same specs to do the homework for you. Why?
So you don't even own or use the earlier machines or the current versions and already you're worrying about future trade-in value? Why is that so important to you? Why not simply just buy and use what you need when you need it? If it's now, fine. If it's not until next year or the year after, that's fine, too. Think about it: is it realistic or important to worry about trade-in value for current machines that you don't even own right now? What do you genuinely need right now for work/personal use? Is the need rather urgent? Then buy what you need now and put the future aside until it actually arrives.
I recently bought an M1 MBP Max because I needed it sooner rather than later and although there were rumors about upcoming M2 versions, at that time there was no knowing exactly when the new machines would arrive. As it happened, sure enough, the M2 versions came within a few weeks after I'd already bought and set up and had been happily using my machine. I'll admit that I did experience a twinge or two of regret that I hadn't waited longer, but in the meantime I also have had the benefit of using my machine, and that in the long run is what counts as far as I'm concerned. With regard to the (eventual, years-down-the-road) trade-in value of this machine? I really couldn't care less, as that is something which won't be a concern to me for at least three years if not longer.
