My reaction:
Seriously it is pointless announcing specs of consoles without showing footage of games and I know they were not going to but then why announce it? Basically indicates to me MS really do not have a huge amount of stuff in the pipeline for E3. I feel like scorpio is an admission from Microsoft they accept they are just not as good as Sony or Nintendo at game development. So instead of compete with them both they are using the most powerful game console to try and entice gamers back. Ultimately this E3 is going to be Power (Xbox) vs software (Sony) and really software always wins.
If they have nothing for E3... then why not save this for E3? Also, was the Pro Sonys admission that their games suck? I'm not sure why one iterative console screams terrible things about a company but the other wouldn't. We all knew these upgraded consoles were coming. MS is launching theirs a year later, of course it will be beefier.
The specs are great for Scorpio but what's most exciting to me are the refinements and innovations DF spoke on. They didn't just wait for better hardware, they really seem to have designed it to work much better for gaming than the Xbox One.
