Citing the the ZDNET article: "On Sunday morning Sony started packing up its 27 PS2s. The show, in Hannover, Germany, officially finishes on Wednesday." This is very misleading if you read it sloppy. Sony did not leave the show. They removed the PS2s, no more no less. The entire Sony booth is 2000 square meters, only 100 square meters where dedicated to the PS2. The rest is still there. This article by German magazine c't explains the situation in much more detail. Use the fish translation if you don't understand German.
