What's Stephen Amell up to at San Diego Comic-Con? The Arrow star will be part of the panel for his series , of course, but today he teased much more is in store.

You know I'm going to be at San Diego Comic-Con International this year, but you have no idea what I'm going to be doing. The Arrow panel on Friday evening is the literal tip of the iceberg. Feel free to speculate. There are (at least) 3 more things on my schedule. Big things. Needless to say, I plan on winning Comic-Con this year. Captain Style.

Heading to a new city this September to meet some friends. Announcement is coming Tuesday.

During a longer Facebook post , Amell wrote the following:The comments on that Facebook status immediately began to fill with speculation on what Amell's other SDCC commitments could be - and quickly turned to a lot of pondering about whether we might get a reveal that he is part of Batman v Superman: Dawn of Justice and the Justice League movie, something many fans hope will occur. Of course, there's no guarantee that is the case, and is being fueled by a prevalent fan desire that Amell's Arrow will be tied into the DC Comics movies, but it's certainly difficult not to wonder what Amell means by "big things."In addition, Amell wrote:Crossovers between Arrow and The Flash are almost a certainty -- the trailer for The Flash has already revealed Amell has a guest appearance in the pilot episode -- so that could be the Tuesday announcement. But we will have to wait and see.In the meantime, Amell also revealed another video of his training for Season 3 of Arrow, with some very amusing video game-inspired decoration.Here's what Amell had to say about Arrow's future when we spoke to him after the Season 2 finale.
