What is the newest Sony Ericsson cybershot?

Tweet

I've been surfing the web for the newest cybershot but i just can't find it (or maybe I just don't know that, that is the newest model). Do you know? I wanted to buy a cybershot, because I used to own one, but I sold it. I know that its camera is great. I love its pictures. I just want to know the model so I have an idea how much I should be saving now. Coz I'm planning to buy a phone on December. Please help me on this one.
