Nope, not unless they make the OGL 1.0a irrevocable and keep the same open status on any future versions. If my group and I decide to continue playing D&D, it will be because I have probably 5 to 10 years of material on my shelves. But the group is very interested to see where both ORC and Black Flag go. We'll be supporting both. WotC can rot if they continue down this path.
And anyone who says "I just play, this doesn't affect me," is, IMO, being short-sighted. If WotC closes off their arena, the droves of new content will be made for ORC and Black Flag, and D&D will simply be whatever content Wizards dribbles out. What's bad for the creators is bad for everyone who plays.
