SES-18 and SES-19 are expected to launch together on March 6, 2023. Intelsat expects the LEOP and IOT period to last approximately 30 days.

Seems impossibly close to Mar 7th Intesat 40eand March 11th CRS-27 dates we have but maybe one of those is slipping?

Intelsat 40e is no longer scheduled for March

The same colleague says that the new target launch date is April 7.

See the Intelsat 40e launch thread.  Inside source has this currently launching April 7.
The word from a colleague with direct knowledge is that Intelsat 40e will not launch on March 7.
Current target date is March 23 but a slip “into April would not be surprising”.
The same colleague says that the new target launch date is April 7.

ASDS 1st stage landing likely?

Different make/model, but same general purpose: Galaxy 33 and 34 launch used ASDS landing.

Likely yes. Other Northrop Grumman GEOStar-3 satellites have (had) launch masses between 2000 and 4000kg. So SES-18 & SES-19 will probably be between 4000 and 8000kg combined.

Also: Likely using this license:
0157-EX-ST-2023
Mission 1589, SLC-40 or LC-39A
Operation Start Date = 2023 Mar 2
ASDS North 28 13 18  West 73 43 45 (GTO/ASDS landing approx. 670km downrange)
"Uses information from" 2087-EX-ST-2022 (Amazonas Nexus 6)
That mission number seems to be in between previous Intelsat and SES C-band launches

Other than this smaller antenna, these satellites look identical to Galaxy 33 & Galaxy 34

Which first stage will be used for this launch?

1052.8 and 1053.3 are manifested to be expended on the ViaSat-3 Americas launch.

1060.16 is presumably still involved in its "deep-dive examination?"

Available first stages, with date of most recent recovery:
1058.16  Dec 17 (perhaps being held back until the examination of 1060.16 is complete?)
1067.10  Jan 26
1069.6    Feb 2
1073.7    Feb 6  Cargo Dragon SpX-27  OneWeb Flight 17 (currently expected to be undergoing conversion to a Falcon Heavy side booster)
1062.13  Feb 12  OneWeb Flight 17
1077.4    Feb 18
1076.4    Feb 27

Edit March 16: It's 1069.6.

The time change just happened at 2am Central Time (The time change for all US timezones twice a year starts CONUS-wide at midnight 00hr00mm on Sunday morning in the Pacific timezone. Everywhere else is by the US Virgin Islands and Hawaii.) in the USA, minus select states and territories which never opted in to the DST capitalism scheme, so the latter is more likely.
