Just to retreat a few posts, when Sony released the PS1 I don't remember anyone saying CD was overkill. CD had already been used by the PC, PC-Engine and Megadrive years earlier, and the 3D0 and Saturn had already embraced CD.
On the contrary, it was Nintendo who were being criticised - and I think the N64 demonstrates why MS's decision to use DVD wasn't wrong.
On the N64, cart manufacturing costs made it unappealing to produce software for the system, and cart space limitations made the production of certain killer apps impractical or impossible for it. DVD in the Xbox 360 does not have an associated cost penalty (probably the opposite initially) and its size limitations are such that it does not preclude the kinds of killer apps that MS need (as has been readily demonstrated). For these reasons we can say that DVD is good enough for this generation.
The hardware and software sales figures say it all.
