I believe somewhere they said every season next year is going to include a raid, which if true I think you can all but guarantee returning D1 raids. No offense to Bungie, but theres no way they are making an entirely new raid with any real substance in only 3 months times. Thats how you get a raid like eater of worlds which I dont think anyone wants again. I think even if its re-released everyone would want kings fall and wrath of the machine. With how well received VoG return was its a no brainer to bring them back since at this point we've had more time in D2 than D1.
