Just to clarify, even if there was going to be a panel talking about P5, it doesn't mean that the title will first be announced there. Consider the fact we might learn the title around the time filming (supposedly) starts in the next several months.

Having said that, the article says So many big blockbusters in 2014 and 2015 will be expected  to show at Comic-Con. That right there implies the writer of the blog is speculating.

So once again, take all this news with a grain of salt.
