This is what first leapt out at me when reading the new article over at Gotfrag. We've already seen the fine folks at Big Download quiz the folks at Blizzard about how Arenas are developing and affecting the overall gameplay of World of Warcraft, so it definitely seems like there's a renewed emphasis on PvP as an e-sport going on. Maybe I just missed the boat on them doing something every year for it... how is this going to work for next year, when Wrath of the Lich King has been out for a while?
We're looking to add new Arenas for Wrath of the Lich King that may be a bit different from the current Arena environments, but we're not ready to go into specifics just yet.
Frankly, new arenas sounds like a good idea to me, but I'd also like to see a new arena bracket. 2x2 has always struck me as being too small to really be anything more than glorified dueling, but I enjoy 3x3 (I'm not terribly good at it, mind you) and find 5x5 starts to get a bit hectic. I think 4x4 could be a fun addition to arenas, but I have no idea how popular it would end up being. The masochist in me would like to see 10x10 brawling, or even 10 man King of the Hill style arena matches where all ten players are hostile to each other, similar to the way Gurubashi Arena and the Maul currently work. It would be a means for single players to gain arena points but would be challenging and a change from dueling.
They're also considering means to allow for spectators on arena matches, which I'd be interested in seeing. The whole article is up at Gotfrag.com so feel free to take a look and see what you think about the future of arena as put forth by the inimitable Mr. Chilton.
