Arms V Fury V Death knights

For the last couple of days I've been thinking about Death knights, and along with that there has been a few discussions amongst us fury addicts about a possible threat to our raid spot.
So i took it upon my self to see what i could find out. And this is a little speculation of my own.

First of all, An arms warrior always seems to be in demand for the Blood frenzy debuff (4% more physical damage on the target), even im asked to re spec every now and then for this. So i guess you could say as long as an Arms warrior knows how to play, rotation wise and proper use of Slam, he will almost always have a raid spot.

Fury warrior dosnt bring anything to a raid that an arms warrior cant... apart from more damage done, but that is more than componsated for an Arms warrior by Blood frenzy. Now this concerns me because with the Wotlk we will see an influx of Death knights all over the place and they are going to want a raid spot right?
So what can a Death knight bring to a raid;
Rais dead - Raises a ghoul to fight by your side. If no humanoid corpse is available, Corpse dust must be supplied to complete the spell. Instant cast. 30 yard range. Costs 2 Unholy Runes. If used on the corpse of a friendly player the player will be able to control the ghoul for the spells time.
Mark of blood - Place a mark fo blood on a enemy, wheneever the marked enemy deals damage to a target, that target is healed for 2% of its maxiume health, lasts for 30 seconds.
Abomination strength - Your blood strikes and heart strikes have a 25% chance and your oblitorates have a 50% to increase the total strength of raid members within 20 yards by 10% for 10 seconds.
Hysteria - Induces a friendly target unit into a killing frenzy for 30 seconds, increasing there physical damage by 20%, but causing them to suffer damage equal to 1% of there maximum health every second.
Frost Aura - increases your frost resistance by 32, while in frost presence, increases the total health of all party members within 45 yards by 3% (6% if second talent point is placed)
Acclimation - When you are hit by a spell you have a 10% chance to boost your party's resistance to that type of magic for 18 seconds, stacks up to 3 times.
Shadow of death - Increases your total strength and stamina by 2%. In addition, whenever you die, you return to keep fighting as a Ghoul for 45 seconds.
Anti magic Zone - Places a large, stationary anti magic zone that reduces spell damage done to party members inside it by 75%, the anti magic zone lasts for 30 seconds or untill it abosrbs 10,000 spell damage.
Scourge strike - An unholy strike that deals 50% weapon damage pluse 6 as shadow damage and inflicting blood plague. Any esisting heal over tim spells on the target become currupted, dramatically increasing the damage done by the disease and removing the healing affect.

Not to mention the AoE abilitys that Death knights have.

So my question is this.. With a new class implimented and raid spots being even tighter, do fury warriors run the risk by being out classed by death knights thus losing our raid spots unless we spec arms and get blood frenzy.

If so the only thing i can think of to fix this is to rework the fury tree to enable us to signifently buff our raid/party members... or put Blood frenzy in a much lower tier in the arms tree (Replacing improved rend with Blood frenzy would be nice as imp rend is crap!)

Having even more competion on plate gear as well will not make gearing ourselfs up to be raid viable any easier.
I fear the fury warrior may die out, unless somthing is changed.
