I've watched the 4E news with passing interest. I don't buy their
products and have no plans to buy their products, so it's hard for me
to get worked up over them.
I do however think that people are over-reacting on a number of
points, and the change in OGL is one. Frankly I thought at the time
that the OGL got out of hand with games being labeled as D20 that had
no real reason to be so labeled. Rather than offering a common
mechanical experience to the buy, the label basically did little at
times except to piggy back upon WotC shelf space. A more firm
agreement would hopefully prevent that.
