I'm not lining up to buy one, but there are some interesting games slated up for the Xbox One. Quite frankly, I think that it's great that Microsoft backpedaled on its bad policies and have improved their product as a result. I recall another company who did something pretty similar with a certain $600 machine they released not too long ago...
At the end of the day, good competition is healthy for the market and great for consumers. I'd rather see all three neck and neck as it would mean they'd all have to work their hardest to retain their marketshare and attract new consumers.
