The Dreamcast was in big trouble long before it was hacked. You could even say the DC was in real trouble back in 1996, when management squabbling was making the process of selecting technology and gaining third party support slower and more difficult than it should have been.
Certainly though, you have to admire the way Sega used cheap and effective proprietory media for the console (its high capacity GD roms), only to give every DC the ability to not only rip said games, but also boot and play copies from none proprietory CDRs. It seemed to take them ages to change the design to prevent this.
Anyway, on topic, Sega's Xbox exclusive games have sold so poorly outside of "the bundle", it's hard to see how a lack of Sega support would have killed it. Halo would still have been the killer app that it was, and the technology gap between it and the Xbox would have been the greatest this generation. DC's dial up friendly alternative to Xbox Live might have had some impact, but again not too much given the relatively small proportion of Xbox users that subscribe to Live.
A successful DC would have impacted most on Nintendo IMO, as the DC would have been a cheap console to compete with GC, while removing some GC titles (such as the very successful Super Monkeyballs and Sonic Adventure 2) and obliterating the GC's entire online presence (PSO 2 and 3). F-Zero seemed to be a pretty big event for Cube too actually, going by fan excitement.
PS2 would have been hugely successful whatever. Even if it had taken a few million PS2 sales (which you could debate untill the cows come home), it wouldn't have made much of a dent on the userbase.
