They're not saying a specific thing because they don't have any specific thing.Capcom, just say "wait another month!", or "let's see in December!" or something like that, so we can stop to raise our hopes for every events.
The only reason there is not to announce something is that it's not final. Capcom hasn't decided anything, but their lower guys don't have the guts to ignore us, which is why they're stuck in the "just wait" limbo right now.
