Are ANT-MAN End Credits Reactions Implying Something Big is Coming For Marvel's Smallest Hero? - UPDATED

Disclaimer: I have not seen ANT-MAN yet and I'm just piecing together my own theory on what the one of the ANT-MAN end credits scenes might be based on what the initial press reactions are to seeing it. However, here is a SPOILER ALERT for anyone who doesn't want to read my theory.

[My theory in this post has been debunked so no need to worry about spoilers and the UPDATE is at the end.]

If you're still with me, let me start by sharing a few press reactions that have brought me to my theory. First one started my intrigue...

ANT-MAN is good. Not a disaster like some expected but also not a homerun. Has a *must see* after the end credits scene.

This reaction really got me intrigued...

A woman who watched Ant Man behind me made no noise during the whole screening, but almost exploded when the post-credit scene came on.

— Todd Gilchrist (@mtgilchrist) June 26, 2015

And this reaction got me thinking and speculating...

Recent Marvel credit scenes have been kind of minor, but ANT-MAN has two (mid-credits and at the very end) that, unlike its hero, are huge.

So what's my theory? It's that in one of the end credits scenes, fans will be teased that Paul Rudd's Ant-Man could also be this guy...

...Giant-Man.

If you're not familiar with Giant-Man he is one of the other hero personas of Hank Pym in the comic book universe and there's been an online rumor stating Giant-Man could appear at some point in Phase 3 of the Marvel Cinematic Universe.

Teasing Giant-Man in an end credits scene makes sense seeing as how that last reaction teased the credits scenes are "huge." To read more about Giant-Man on Marvel's character page, click here.

Again, this is just my speculation but it's a logical guess nevertheless.

UPDATE 6/26/15 11:53 a.m. ET: I have been told by someone who saw ANT-MAN at one of yesterday's press screenings this IS NOT one of the end credits reveals.
