I remember that guy, he was crazy
Anyway, don't you remember spring 2020 when we were waiting for iMac update? We got shortages of it throughout the year few times but the iMacs were updated in august. These things usually don't indicate imminent refresh.
Sure, sometimes they do but most of the times its just inventory shifting. Its not valuable metric.
Having said that, I care more about what Gurman tweeted today so perhaps there is a slight chance for iMac next tuesday but not for the 27" model. Rather odd but it would signal that M1X is going to low end iMac (24") and the bigger model will get M2 variant later this year. Would be logical in terms of tech but illogical in terms of marketing.
Few more days left
