It's definitely going to be longer thanks to system requirements that are out of my reach right now. I just learned from a box art leak that MoP will require a dual-core processor and a better graphics card than what I have. As you may or may not know, my income is nearly non-existing as I have no job and chump change from my parents here and there. So getting these upgrades are not as easy as one may think. Not to mention that its risky to update my CPU with an five year old computer and it's probably on it's last limbs (just bought a sound card since the on-board sound died). So I practically out of the gaming deal of this.
I probably won't come back to this game at this rate. It's a shame, but I guess they have to upgrade the game's programming eventually. Just didn't think it would be at such a bad time.
