Punk will be a heel because WWE is predictable. Look at the 'looks at guy he just hit with finisher slow stare' at the end. That is ALWAYS a heel turn and WWE isn't creative enough for it not to be.
Also, I've studied the tapes, and I've come to a decision.
Stone Cold's character in 1996 is the greatest character in wrestling history. Possibly even top 10 characters for TV history. Better than Rock, Hogan, Flair, Macho, and Bruno in their prime. Of course, I won't just say this without any kind of posts backing it up, so these are what I thought while watching a bunch of 1996 matches/ppvs.
I don't think you can solely give Austin credit either. It was a perfect storm of events that made him perfect for this year. The perfect torch bearer. Austin was originally Stunnin' Steve in the WWF. He had a short stint where he worked for Dibiase and beat the shit out of people. He did an awesome job of it, but he was just the typical heel and it was more about Dibiase than him. He also had blonde hair and looked like Human Bender from Futurama. He was noticeable but nothing big. This was before the internet as well, so your memory of people as a mark back then usually relied on merchandise. To my knowledge, there's no Stunnin Steve merch and that's perfect. Sure, a couple people might have recognized him as Steve Austin, but they were in the minority. Most people thought this new heel was just 'some guy'. And that's the first thing about Austin that's perfect in this year. His look. In 1996, WWF was still full of guys wearing bright, neon colors. Hell, their fans and their stage was colorful too. It was like a cartoon brought to life and most everyone had ridiculous Fantasy Novel hair or generic 'haircuts'. Then you've got Austin. This mother fucker comes out in the most basic gear. Shaved head, goatee, black trunks, knee pads, boots, and that's it. It's such a huge contrast to the ring and other competitors that makes him stand out like a sore thumb. Unlike Orton who they try to make a 'loner' who just looks like yet another douchebag in black tights and silly tattoos. Austin looked like a guy who liked to get in fights at bars and decided to wrestle because it was another way to beat people up, so he put the minimum amount of effort in attire so he'd be accepted into the WWF ring.
The most memorable parts were probably his promos and in-ring work though. Austin wasn't the best wrestler in the world, but this is Austin in 1996. This is Austin before he broke his neck. People seem to forget that he used to be more than punches, knees, stun guns, lou thesz presses, and stunners. He used to be technical enough to keep up with guys like Bret, Owen, and HBK. And that reminds me of the promos, Austin was awesome because he was booked like a loner. He started off as a heel, but he was the modern day Dusty Rhodes. He was the blue collar guy that fans could relate to even though he didn't want to relate to fans. He was the 'Die Hard' of wrestling. Even though you couldn't, you felt like you could be Austin. And Austin was introduced as a heel, but what was awesome was, even though he got cheered, he never TRIED to get cheered. This is Austin before his corny catch phrases, t-shirts, slogans, etc. Even in 98, Austin was corny compared to 1996 Austin who looked, honestly, terrifying. Austin's character HATED Bret Hart, and the booking was so good that he would come out during Hart's matches just to fuck him up. It felt like the two legit hated each other, but it was also awesome because Austin's character hated HBK too. HBK was a face, but he was a face like Cena that a lot of people didn't like. It was mindblowing that this character was dumping on the biggest heel in the company AND the biggest face in the company. And they booked Austin so well because of how he looked. He wasn't too big so they didn't book him as a 'monster' who dominated. He wasn't too small, so they didn't book him as an underdog who only won when it mattered. He won enough to look like a serious threat, but he lost a bunch too which made him look hungry and vengeful.
These promos would MAKE the Atittude Era. A lot of the same props are even used for the Raw is War entrance
Survivors Series 96(I honestly think this is the best WWF promo of all time)
On the 8th day, God created Stone Cold and I'm rewriting the book.

Alright, I think I'm done blowing Stone Cold... For now.
