Starting with the Cage match upgrades apparently now you can dive from the Cage mid climb if your opponent is up. The other new addition is a climbing mini game similar to the way THQ used in older games back during the SVR series. But in recent games that mini game had changed and honestly I don't remember what we did in Cage matches during recent games. However, just by looking at some pictures and gameplay it does look like these types of matches will be a lot better. Also I want to point out that I know in the Legend of Wrestling franchise you could dive off the cage mid climb and I'm pretty sure you use to be able to in WWE games not sure when though.
As now you can fight on all four sides of the cage as oppose to just the right and left side like you could in previous years due to the size of the cell. Another new addition is escaping the cage is a lot simpler as you have the ability to send your opponent through the panel if the move does enough damage. This will make the match a lot more fun in my opinion because now you don't have to expend a finisher to get out of the cage and can do it whenever you like. The last change that they are bringing this year is that pretty much all the roof panels that are above the ring are breakable from the roof similar to the way they did it in Day of Reckoning. This means that not just the middle panel like in past years is breakable, but I would say close to 50% of the roof might be breakable depending on the amount of times you want to take that fall.
