Blizzard and Bigpoint are the two latest companies to throw their weight behind the upcoming GDC Online event.
The World Of Warcraft studio will send its project director Greg Canessa to deliver a keynote lecture on building the Battle.net online facility.
Meanwhile, Bigpoint CEO Heiko Hubertz will deliver a business lecture on the untapped potential of the protracted and complex European game market.
The deadline for early bird rates is today, September 1st.
Hubertz and Canessa already add to a promising line-up for the US-based event.
Among others, Bungie will attend the show to discuss narrative, while Zynga will make a rare (now rarer) public appearance to discuss its latest world-beater FrontierVille.
And Playdom – Zynga’s social game rival and Disney’s latest acquisition – will also make a first public appearance since its buyout.
GDC Online runs from October 5th to 8th.
