There have been new forms of DRM before that took as long as a year to crack.
Now that the discovery phase of this DRM is over, it's going to be easier and easier to crack these games.
Given that the game is nearly cracked, that Ubisoft had to give away lots of games for free as compensation for its failing server, and that it was reduced to just £16 after 3 weeks which suggests poor sales performance, I would say that this DRM has not been successful in any way. And to top it off they've taken a PR hit for angering their paying customers, and made them less inclined to buy future games after encountering these problems.
And then EA saw all these problems and put it on C&C4, a game that already sucked in the first place
