Reading between the lines in the article and the FAQ it seems this indeed will happen:

http://posterous.uservoice.com/knowledgebase/articles/56001-...

> What happens to my Space? Will Posterous eventually shut down?

> You can use your Space(s) exactly as you have in the past. We’ll give you ample notice before any changes or disruptions to the service and we’ll provide specific instructions for exporting your content to another service.

Notice they don't actually answer the question.

> Posterous engineers, product managers and others will join our teams working on several key initiatives that will make Twitter even better.

Sounds like they'll be working on Twitter, not Posterous. It doesn't say anything about people at Twitter working at Posterous, so it doesn't sound like a merge.

They can't exactly promise to remain up forever. That's not in their control post-acquisition.

There's a big difference between "Um... ah... we'll tell you before we delete everything" and "We've received assurances from Twitter that they intend to support the project for the foreseeable future", though.

[jamesaguilar]

Yes, but if they haven't received those assurances, there's no benefit in highlighting the fact (for either the users or Posterous), and much potential harm if users spook and Twitter later decides to continue supporting it.

They would have just been through a negotiation process for acquisition. Of they didn't seek out assurances or none were given I find it highly unlikely there will be any result but a shutdown. If twitter was interested in posterous the product, it would have been front and center in the announcement.
