Found on Das Spielzeug's online catalogue. Translation via Equestria Daily:
It's now 30 years since "My Little Pony" shows up and bringing Girls into the colorful world of friendship. It began just with a little plastic toy of the colorful Ponys. Today it's inspiring with TV Shows and a huge and colorful lines of products. In September, Nici will bring out a 20 piece-set of "My little Pony". With that, three very popular Ponys "Pegasus Rainbow Dash", "Twilight Sparkle" and "Pinkie Pie" from the TV Show will be coming to your home for cuddling and loving.
Under the Pinkie Plush:
Nici will publish the plush collection in the second half-year of the Ponys from "My Little Pony".
The article above cannot be located in the February issue (which may mean it was in an earlier edition) so there is no confirmation outside of this screenshot. Even so, it's a beautiful looking plush! Easily the best G4 plush we have seen so far. Hopefully they will see their September release, and perhaps a wider release from there.
