EOY 2017 - Cannonlake Y
Q1 2018 - Cannonlake U 2C, with ramp up over the year, meeting their claims of "HVM 10nm 2018"
It's probably more like a paper launch Cannonlake Y in end Q2 2018, with volume in H2 2018. U likely will get canned. The EOY 2017 stuff is likely something that's not sellable like a 2+0 Y Celeron part but they are selling it because BK said they would ship something in 2017.
Q2 2018 - Coffeelake GT3e and 6C GT2
Launch of CFL 6+2 is January actually. I think 4+3e is Q2, but it'll be small volume for sure.
BTS 2018 - Coffeelake 8C Desktop
That's probably about right.
*GT3e takes extra time to make. They always came later. With Icelake generation we have the possibility of eDRAM being replaced with HBM.
I have to think Iris in general is going to get canned. Especially now that AMD is reasonably competitive on the CPU side there is no reason to think OEMs would bother with Iris when AMD would be so much faster in IGP gaming.
