Sony just announced the Xperia Z1s and the Xperia Z1 Compact at CES earlier this month. Now it's looking like they've got a couple more flagships ready to be announced. Right now, all we know are the codenames, which are Sirius and Canopus. Many believe that the device codenamed "Sirius" is the new Xperia Z2. However, we're not really sure what the Canopus could be. But it was certified for KDDI au, which is Japan's second largest carrier, according to Blog of Mobile.
If you haven't heard of Blog of Mobile before, they have leaked out some great information in the past, and are normally pretty reliable. But we will still warn you that this is a rumor/leak and so we must treat it as such. Blog of Mobile is reporting that KDDI's Canopus features LTE, WiMax, WiFi 802.11 a/b/g/n/ac, Qualcomm's quad-core Snapdragon 800 processor, and the version of Android it's running is unspecified. But we're expecting Android 4.4 - KitKat, since that's what the Xperia Z2/Sirius is supposedly running. They are also stating that the Canopus is going to be sold as the Xperia SOL25. They currently sell the Xperia SOL23 which is the Xperia Z1.
According to another Japanese blog, FXtec, the Xperia SOL25 is going to be the Xperia Z2. Now that is also a rumor, but does sound likely since the SOL23 for KDDI was the Xperia Z1, it would make sense for the SOL25 is the Xperia Z2. They also post a render of what the device might look like (which is pictured above), and it does look really nice. But remember that's a render and more than likely not going to be the final design.
We've heard rumors lately that Sony is going to be announcing the Xperia Z2 at Mobile World Congress next month. Which is likely, especially since at CES Sony only announced the Xperia Z1s (which is the Xperia Z1, but exclusive to T-Mobile USA) and the Xperia Z1 compact (also known as the Xperia Z1f in Japan). So we'll be on the lookout come Mobile World Congress to see what Sony has planned for us.
