EWR-SVQ was rumored a few months ago and today would be the day to announce it, if it's happening. I'll go on the record with a few guesses:
Seasonal:
EWR-NCE 763
EWR-SVQ 752
EWR-BUD 763
DEN-ZRH 788
SFO-BRU 772
ORD-KEF 752
ORD-ATH 763
Year-Round:
ORD-TLV 772 (similar schedule to IAD with 3x to launch; late evening departure, after 2230, and early AM arrival, before 0600 can be accommodated at T1 and T5)
SFO-DUB 789 (checking another tech hub off the list)
DEN-LHR 789 ??? (can United get the slot, or does any existing city lose a winter frequency?)
EWR-BLR 789 ??? (is the India market ready for so much more capacity, with a summer start? Would be UA's longest EWR route, surpassing HKG)
EWR-TPE 789 (if EWR gets one year-round long haul, this would be my guess)
We'll know soon enough... I'm also interested to see what seasonal routes will return. I think EWR-PRG is a lock, and I'm hopeful EWR-NAP makes the cut as I didn't get a chance to try it this year.
I don't expect the following at all, but would be glad to see them:
SFO-BLR
SFO-SGN
SFO-MNL
SFO-NGO
ORD-ICN
EWR-CAI
DEN-CDG
EDIT TO ADD: I don't expect everything... but I hope to hit on a few
