So, they have announced that online gyms will be a part of the game in a similar way to what was seen in MMA.
 
Hopefully Jeff will create a gym when he reviews the game (assuming he will).  I, personally, would love to be a part of that.

Oh, I thought you meant a pokemon gym...

" @Tonylope:   Sure, if a pokemon wants to get in the ring.  Actually, it would be pretty awesome to use game face to create a boxer who looked like a pokemon.... or would it? "

I am all for this.Seeing as Jeff reviewed FNR4 though I don't know if he will do FNC, he usually doesn't review sequels/episodic games.

I don't think anyone else in the office is as interested in the fighting genre as Jeff.  Back at GS it could have been Ryan McD or even Justin Calvert, but here I don't see anyone else wanting to do it.

What happens in the gym? I didn't play mma, but is it just a place for sparing/training with others online? Sounds pretty good if that is the case.

Lol does this mean that the game will let you create your own custom gyms?

The gym lets you spar with other members.  They also have a gym rivalries system built in the game in which one gym competes with another over the course of a week or a weekend or something and they can earn points for their gym.  I think the gym points will be put toward upgrading your gym with new equipment so boxers can train better and with customization items.  There are some more details on the official website, but this is what I recall from reading it last week.
 
Also, I did a little research and the guys here definitely do review the sequels of games they previously reviewed.  Just as an example, Jeff reviewed Little Big Planet and Little Big Planet 2.  He also reviewed Street Fighter 4 and Super Street Fighter 4.  So, I bet he will be reviewing this.

I created a gym called "Giant Bombs", it's public, not sure how you join but feel free.

Will join any PS3 gym.
