The HD-DVD thing is totally backwards. Putting HD-DVD on the console would only have delayed it and made it more expensive, which would enable the PS3 to crush it.
360's head-start was very important for two reasons:
1- Getting a lead in installed base without having to compete against another console of the same gen.
2- Getting developers to learn 360 development, without the PS3 competing for their time.
Were these advantages to disappear, the 360 would have been an easy kill for the PS3 - many customers would just go with the most known brand, PS, and developers would focus more on the PS3 since the PS2 was so successful.
Conclusion: DVD was the right choice for the 360.
