I agree with your premise but must ask....if every legitimate connection from a PS or an XBox comes from a MAC address already known to Sony/Microsoft by virtue of the fact that they assigned/recorded such addresses at time of manufacture could they not set up a firewall/filter that rejected traffic from unknown MAC addresses?
I also confess to being mostly unfamiliar with the DOS-ers methods i.e. are they using hacked consoles or are they using PCs running scripts etc.?
I realize spoofing etc might defeat such countermeasures in part and that the vast majority of consoles are behind routers, gateways, etc.
I know that a variety of sites, some legitimate and others less so, have fought these battles in the past and achieved some semblance of immunity.
That would do a lot to help; the problems that would crop up are (a) MAC spoofing, (b) middle-man connections [proxies, routers, etc] and (c) the possible legal implications, as this would effectively deny 3rd party adapters.

While I am a programmer, I am not particularly knowledgeable about black hat
operations, so I can't say anything with certainty there.

I think what they've done in [most of] those cases is essentially widen up their bandwidth, and implement some sort of filtering.
