Sony-made smartphones are back in the news, and this time with brand new details that look quite heavy when compared to the previous rumors and speculations of the past.

Per reports, a brand new list from the Indonesian Ministry of Communication and Information's Web site states that Sony's HuaShan smartphone is expected to be released as the upcoming Xperia SP with model number C530x.

Apparently, the list also contains information about a certain never-before-mentioned Xperia L that is also set to arrive.

According to all the previous reports speculating about the existence of the Xperia SP, the SP is expected be the higher-end version among the two smartphones mentioned. The device is said to sport a 720p display, with a dual-core Qualcomm Snapdragon S4 processor clocking at 1.7GHz.

The Xperia L, featuring a model number C210x, according to the same report, could arrive outfitted with a FWVGA display of 480 × 854 pixels, a dual-core Qualcomm Snapdragon 1GHz processor, and run Android 4.1.2 Jelly Bean.

Now, it may seem that the specifications for the Xperia SP are more or less similar to the ones for Xperia SL, but it is to be noted that the specs for SP are still rumored, and it could also be that the SP is the Indonesian version of the SL. As of now, nothing can be said with surety as to what kind of specifications will be featured on both SP and L, at least not until they are made official by the company.

Sony, only recently, revealed the price of its upcoming flagship device - the Xperia Z. The company's UK Web site stated that the Xperia Z will cost £529 (about $830) in the UK, but there was no information about the device's launch, as it was only mentioned that the device is "COMING SOON."

"With the flagship phone (Xperia Z / ZL) out of the way, these two models stand a good chance of being unveiled at the upcoming MWC and we'll be on the lookout for them," a GSMArena report states. On a side note, what's with Sony's naming scheme anyway?"
