From the broadcast I can see we've got another version for Saint Paulia coming up in the future.
EDIT:
I've joined halfway, so I'd need to go back to watch the whole thing, but there are a few interesting news.
For example, guaranteed current event 6* gacha deals are coming back.
Dipladenia's getting a new voice actor.
We're getting a new collaboration this year, though we don't know with what for the moment.
The rates for rainbows in the standard gacha and event gacha will be raised to 2%.
For pickup gachas, this will be raised to 1%.
The memory exchange shop will see some change.
There will be another affection level that has something to do with an "eternal promise".
For the Valentine's event Kitsune no Botan and Dipladenia are coming back with new forms.
For another event, Nightshade and Larkspur will also get one, followed by Walnut later.
Blushing Bride will get one too, possibly in the same event as Saint Paulia.
The code for some free silvers:

By the way, they had a regular party with the players during the broadcast, which was quite a surprise to see.
