Upcoming updates

The following is a list of upcoming updates, derived from official Jagex content:

Smithing

 * Note: Some mining updates have already happened- Dragon pickaxes, Concentrated coal rocks, Concentrated gold rocks, and, for smithing, the update in the success of creating Iron Bars from Iron Ore...

Unknown update

Hiscores
This might refer to the recently released Adventurer's Logs, or the Barbarian Assault statistics.

XP counter
the xp counter was released along with the new skill on 12th april 2010

Elemental Workshop III
It has also been hinted at in the Chaos Elemental's suitcase; see http://runescape.wikia.com/wiki/Letters_to_the_Chaos_Elemental#Letter_13_.28Suitcase.29

Several more Grandmaster quests to come

 * One of the Grandmaster quests Jagex said to be released is Nomad's Requiem, which was released on 11 January 2010. However, this is not the level 80 requirements quest, as none of the requirements for Nomad's Requiem are level 80 or above, simply recommended to be that high.

Dragon ore / dragon bar
This may be known as the update towards metal dragons as well... but who knows?

New mage hats

 * Note: the fact the hats will be released can be indirectly derived from the answer. There was no question about the hats, though Mod Mark showed interested in them. It might be a strong hint, and could be part of the combat rebalancing updates.

2010: Year of skill completion

 * Note: this was said in 2009; the 'aimed update until the end of this year' refers thus to 2009 and not to 2010.

More Elite diaries to be created
Jagex asked on the future updates on RSOF for player's suggestions on possible future elite tasks and rewards. As this thread is posted in future updates section (and not suggestions section) and there's a develop blog in the same section created, it is to be assumed there will be more elite diaries in the future.

'''NOTE: The threads Concerning questions and suggestions in relation to the Elite development blog have been deleted. Indicating that Jagex May Have already decided which suggestions would be suitable for the the Elite tasks.'''

Barbarian Assault, Gnomeball, Trouble brewing and Castlewars Updates

 * Note: the Barbarian Assault update was released on the 19th of January 2010.

More fairy ring teleports

 * Note: it sounds plausible this update will come along with Fairy Tale part 3.

Improved Fairy Ring Teleports

 * This implies that FTP3 might introduce staff-free fairy rings

Magic Graphics Update
{{cquote2 Mod Mark: Yes, we plan to add particle effects and bloom aspects to spell animations, bringing them up to standard. Our artists mention it weekly! Mod Fetzki: It is a massive task and a unique challenge to get this done to a high standard, in both Standard and High Detail modes. The early prototypes look great, though! {{cite web }}
 * 4 = Mod Mark and Mod Fetzki
 * 1 = Amirul179: Will you update the magic animation to make it more unique and powerful? as the old one doesn't fit RuneScape HD anymore.

Dragon graphical rework
Mod Knox's response to a thread about the new look of the Tutorial dragon.

Fairy graphical rework
Mod Tytn's November 2009 Development Blog announces with the release of Fairy Tale III that the city of Zanaris will be updated along with the inhabitants, constituting mostly of fairies. In a Development Diary released earlier that year, Mod Joe presents some screenshots of the what Zanaris would look in the near future. Although not confirmed, it is expected that in 2010 the third part of the Fairy Tale quest series will be released, along with a Zanaris graphical rework that includes the fairies' homes and landscape.

Forum

 * A recent update had allowed greater forum access to players. Players could now post in the forums having at least 5 million exp in total.

Fairy General
The fairy general was confirmed to be a character in the unreleased and untitled Fairytale III in the Fairy Tale III: Subtitle Yet to Be Approved Developer Blog.
