I done tweeted that twitter thing. I'm sure they're well aware of people's opinions on the matter, so let's hope they are able to still do something.
Sony need to really pick a good time to reveal their DRM stance If it's an awesome one, they can either do it now and show up Microsoft, or at E3 and win everyone over in 90 minutes.
If they're adopting the same measures that we think Microsoft are, then they should get that out of the way so that people's expectations are appropriate for E3. Of course, they need to be sure of Microsoft's stance before they say anything, so I expect Sony will wait until after the E3 conference to clarify any negative stance on the subject and just hope that the conference will carry them through.
Not that any of this matters to the rest of the market. I'm really interested to see how they respond to this news, and I'm guessing it will be a similar response. Mostly because of the used games thing.
What's going to be super important is the right media channels communicating what each console is offering/restricting and letting consumers know how it affects them. They'll have to report positive news about Nintendo, though, so that might be a conflict of interest...
