The title pretty much says it all. According to the report:
the service will encrypt all messages, phone calls, photos, and videos moving among [the devices].
Moxie Marlinspike is involved, so they have a chance of getting it right, and no one, even WhatsApp, will be able to know what you”re saying, texting, viewing, &c. (Unless, of course, your widget is running malware, or the opposition can get their mitts on it.)-: They claim this is available on nearly a billion devices—this is a really big deal.

What happens, if I reinstall WhatsApp for some reason? Is there any way to download my old messages and re-import (e.g. on the new device)? Does WhatsApp by any chance (officially!) store the encrypted messages? Can I export ma own key and import it on a new device (or just after the installation)?

It'll give you a new key. There's an option that, if enabled, will warn you that your contacts' keys have changed if they have reinstalled.
