Well, not so fast. Beyond the obvious question of "have they really tested systems and whether they'll bear the proposed load" (not while the system is live they haven't), you've got the reality that the system may support 50,000 users per day, but for the system to get seven million people registered by the deadline, simple math says they'll need to achieve.....60,000 people per day. Plus the load of people who browse but don't sign up the first time, and you can figure that the system will still be seriously overloaded.
Add to that known security issues, and the fact that more and more people are "unexpectedly" (to those who don't know the law's perverse incentives at least) losing their insurance, and it would appear that we're going to need to rename "SNAFU" as "SNAOU"; system normal, all Obama'ed up.
Which is, ahem, what anyone paying serious attention to Mr. Obama's curriculum vitae could have told you in 2008 or earlier.
