Alternatively, you have three choices: one that's traditionally lawful, one essentially neutral, and one that appears fairly chaotic.
Lawful
evil. You forgot the evil part. Devils are fairly insistent on that point.
And make no mistake, the flavor in the article was Evil. Capital 'E'. Selling your own soul to a dark being is "not good", and selling other people's souls / sending them to Hell is straight-up, do not pass Neutral or collect 200 gold pieces, Evil.
As it stands, we have three possible power sources: Infernal, Shadow and Feral. Infernal is clearly evil. The other two we can't say for sure yet, but we know that the Shadowfell is the realm of death, decay and undeath. That doesn't bode well for their 'goodly nature.' Feral is most likely CN, NN or alignment-agnostic.
I really, really hope that "Boone of Souls" is an infernal-only power. But I am not hopeful that the Shadow (undead/necromancer) Warlock won't be equally distasteful. That leaves the Feral Warlock / pseudo-druid as a playable PC. One in three.
That's not a good ratio. The 3e Cleric has plenty of non-evil alignments and deities to choose from. As far as I was concerned, the evil gods were there for my NPC-making needs. Not for PC consumption.
Without having seen the rules, I am still hopeful that you can play a good warlock. But the fact remains that it seems you will be playing "against type", and possibly at a mechanical disadvantage relative to your more ethically challenged peers. Much like a "good" Necromancer, who won't use half the spells his evil brethren do.
As it currently stands (and again, without having seen final rules), the Warlock seems like a waste of PHB space better spent on a Druid or Monk. He would be much better as an Iron Heroes' Villain Class.
If you haven't picked it up yet, no, I do not allow evil PC's in my campaigns. They're disruptive and make the game less fun for other PC's. I also don't find it fun to DM for an evil group. And yes, there is a real difference between good and evil, both in the real world and in D&D.
