I'm hoping for a revamp in 6.0, but for right now all we're going to get are band-aid fixes and slight tweaks to improve our dps. As it stands right now, there is no reason to bring a hunter unless you're lacking in other (read: BETTER) classes and/or said hunter outgears everyone by a significant margin. As Truefire said in a previous thread about hunter dps (I'll edit this post and put the link in later on), the only reason to really bring a hunter during progression was so that he/she could soak up mail agi gear and/or if said hunter is a good player.
I can't say what's going to happen in the future, but for the rest of this expansion Blizz is going to continue to "turn knobs" so that hunters will be somewhat viable for raids. I don't know if hunters will be in the same position in SOO (Siege of Orgrimmar) that they were in in TOT. I hope not, but we'll see. I fear that unless hunters bring some kind of useful raid CD, they will not be brought to raids unless their dps is just too good to pass up, which hasn't happened yet.
Disclaimer: I'm talking about 25m raids here, more notable 25m raids that are doing heroic content. Hunters will ALWAYS have a spot in 10m raids due to the nature of the buffs/debuffs they can bring via pets and the fact that most 10m guilds are casual and don't have the ability (or desire) to stack the best classes.
"We brought a hunter to progression for two reasons: to soak up mail agi gear and because he is a very good player. Also, because he was able to soak up all mail agi gear, his ilvl was at least 3-5 higher than most people during progression. A hunter with better gear than most of the raid is worth a raid spot, but if we had the option, we would bring only warlocks and rogues with 525 ilvl over hunters with 532 ilvl (my warlock's ilvl vs dyv's hunter during progression)." - Truefire
