dnaumov writes "According to this article on ZDNET, Microsoft complained to the show organizers, Hannover Messe AG, that Sony was breaching show rules by letting people play on Sony PlayStation 2 game consoles. While Sony has been letting people play their consoles at CeBIT for the past 3 years, that didn't really bother anyone. However, MS seemed to not like the fact and filled a complaint. What makes this even more funny is that Microsoft officials denied that the company had complained to the Messe. but the show organizers confirmed that Richard Roy, vice president, corporate strategy, had complained. This effectively forced PS2 out of the show and Sony started packing their bags on Sunday. Microsoft was also displaying their XBOX console at the show."
