I'm also waiting for a new iMac.
But there are no new graphics cards which they can use:
So my guess is WWDC 2019
But there are no new graphics cards which they can use:
- AMD Vega? Already in pro and normal iMac won't handle. Especially when they change the form factor to be even slimmer.
- Nvidia? Don't think so. Apple lets AMD create GPU's for them now, like they did with the Pro. And even if they did switch to Nvidia, I doubt that they would put an >2 year old card in a new iMac. New Nvidia cards are far away still.
- No new GPU? Doubt that, never happened before.
So my guess is WWDC 2019
