Nobody can ever say. It's up to Jagex.
A recent game they made is War Of Legends. It MMORPG, but it is quite different from RuneScape; check it out.
Yes, there is because Jagex wants it so more people can play.
Definitely it is very successful. According to JAGeX, Runescape will be their main focus until, 2012. After that, it may become what Runescape classic is now, basically, abandoned. JAGeX has 3 other M.M.O.R.P.G.'s "in-the-works", one being Mechscape, the names of the other 2 haven't been released, as of, February 2009.
Actually, you can buy Ultimate Game Cards at Netopia. They sell for 500 and 1k. You can use this to purchase membership by choosing the pay by cash option in Runescape
the abyssal whip is more powerful, but the dragon scimitar is around about 3mil cheaper. I would recommend buying the abyssal whip if you have 3mil to spare. If not then going for the dragon Scimitar would be a good idea, due to the fact that it is not that much less powerful but is a lot cheaper, and both of the weapons have the same attack speed.
You can unblock it by going on Jagex's account recovery feature, you will be asked security questions to make sure your that accounts real owner first though.
I believe it is impossible, at this time, to simply unlock your account. Going to the forums and talking to some Jagex Moderators might help, though the account just might be lost.
You can cancel Runescape membership by going to "Account" on the Menu, then clicking "Account Management, then "Account Information", then click cancel subscription to cancel your existing membership. Contrary to what this message previously said, the email Hexfreak2@gmail.com is not the email of a Jagex Staff Member, the Jagex Staff will NEVER ask you for your account name and password, keep in mind hexfreak2 is just a scammer who wants accounts.
No one knows what the newest skill is yet. It will be let out Mid-2010, or Late 2010. But so far, no one knows what it is except Jagex, the devlopers of RuneScape.
Epicbot is down for to long almost for a half year because they cannot fix the problems JaGex gave them because of the new runescape update "botnuke"
Jagex is making a new game called Stellar Dawn.
