This Matrix Online + Sega crap is not the big announcment.
The people (such as gcadvanced.com) that take pictures like this, dont you think they would post news like "Sega Logo on bottom of Matrix Online poster" instead of just taking a picture and leaving it at that?
Dont forget too, this is hardly a big announcement or something to get uber excited over. Seriously:
"We at Sega are co-publishing Matrix Online!!!"
Its not exciting and it means jack to GCN owners, as we all know nothing online is comming to the GCN any time soon, expecially something as big as this.
