Is there any information known about the weapons used by Tempestarii?

In the latest Warframe update – Call of the Tempestarii – Tenno can embark on a quest of the same name and investigate strange events taking place in the Corpus Proxima. However, considering the update released as little as 2 days ago at the time of writing, many Tenno might have not gotten the chance to play through the quest yet. If my use of spoilers isn’t in place, I apologize in advance.
