Surprise or anything is just irrelevant, you want more people to actually come and promote your stuffs. Most TCG animes have already had their teaser for a long time now, it would be unwise to not at least reveal a teaser for the new anime before a big presentation like this. You want as many people to join and promote your games as possible.
