They had a scheduled launch event today at Blackfriars.

Launch of what, though? Running some of the trains in service from
now onwards; just running one today in service; or not actually
running any at all in service yet?

Press preview, the Roger Ford "Fist of Quality", etc. I didn't see any
announcement about entry into passenger service.

The verb used the most in the tweets was 'introducing'.

"Starting service in the next few weeks" says
https://twitter.com/TLRailUK/status/735141673236332544 which is the most
specific not actually a date I've seen so far.

That's potentially later than any of the possible interpretations of
"late Spring" published recently, the latest being four weeks away
currently.
