According to Swedish technology site MKF, Sony Ericsson is planning the next major launch for it’s new phones during press conference on June 14, in Berlin.

According to Sony Ericsson “the latest developments within photo and music” will be presented. Let’s speculate a bit what these developments may actually mean.

The latest development in photo is, most likely, the long overdue 5 megapixel Sony Ericsson K850i Cybershot phone. The SE K850i was spotted in the wild this March.

The latest developments in music for Sony Ericsson can not be without the new Walkman phone models. And right now we have an information about a couple of new Walkman sliders that should be ready for sale this month.

The first one is Sony Ericsson W999i Walkman Slider that has surfaced on the net this April and was spotted on official 3GSM Association site last week.

Another one is the rumored Shinobu Walkman slider, that was found on the shelves of a Polish cellphone retailer last month.

And of course there’s a long awaited Sony Ericsson M610 (Lizy) 3G phone, that has been approved by FCC already.

Well, I’m not sure that all of them will be announced on June 14, but all of these phones are long overdue and seem to be ready to go on sale pretty soon.
