It just shows AMD feigned indifference to the high-end only because they didn't have a competitive part. I don't think anyone expected AMD to can R700, its just a matter of when they'll get it out and how competitive it is then.
AMD didn't "orphan" its "dustbuster" - 2900xt - and we can expect them to continue to support CrossFire and X2 configurations. Their r700 is a sure bet to eventually show up as X2 - even it it kills 9800ultra at launch
[unlikely to kill the ultra]
... as long as they stay in business.
AMD did orphan the 2900XT but it wouldn't adversely impact support going forward since its still only a single-card configuration that doesn't rely on CrossFire for performance. Its still R600 path, so as long as the 3850/3870 are supported the 2900XT should as well. Don't forget there were rumors even before the 2900XT was launched that ATI would pass on R600 at 80nm or w/e it is and instead go right to 55nm, which is exactly what RV670 is. Instead they released 2900XT on a limited run, probably because the 55nm RV670 wasn't quite ready.
R680 is at risk however given the current CF/SLI support situation, since its a CF solution with a specialized driver that shows it as a single-card solution. That means ATI will continually have to tweak its drivers specifically for the 3870 X2. Given the massive performance increases optimized drivers and profiles can make with CF/SLI, the R680 will have to pray it doesn't become an oversight in the future.
As for R700 being a sure bet to show up in X2 configuration, again, I wouldn't bet on it. That really depends on what kind of transistor count and thermal envelope we see with the next-gen cards. Keep in mind this generation of X2 parts are only made possible with optical shrinks of existing architecture and are essentially a stop-gap until the next gen.
