Minor spec bump are not really compatible with Comet lake chips unless limited to 65W versions because an 125W would require an internal redesign. I also understood that comet lake required a new motherboard which is not a spec bump anymore.
There are always new components next year so that argument is weak. An ARM based iMac will look different than an intel base iMac to avoid confusion so a redesign next year of intel based iMac is just as likely as today or at WWDC2020.
An iMac update is not really a big thing happening and maybe limited in the mainstream media. Tech media should have no difficulties to separate iMac and civil unrest. An iPhone by contrast that reaches mainstream media is an entirely different affair.
