We brought you the news that Sony Ericsson had a new Walkman slider in the pipeline when a photo of it mistakenly appeared on the GSM association's website.

Well, looking at the invite it above seems it might be announced as soon as this Thursday.

According to forum posts this event is going to be the launch pad for not only the Shinobu handset but three others.

The "Sofia" is apparently a HSDPA-enabled phone with 5 megapixel camera, and "Anastasia" and "Mooi" will reportedly also be joining the party on the 14th.

We just hope they're as pretty as their nice friend Shinobu.

We'll bring you more on Thursday.
