My only fear with the invite only launch is that Facebook will have enough time to announce some of it's own changes before people get an invite to Google+. Although Facebook users are unlikely to (attempt to) delete their account unless google+ gains huge popularity. Google+ may just become a compliment for must Facebook users who use circles for their inner circles (perhaps family or co-workers). With hangouts I personally would only video chat with a select group of people falling into three circles, close Friends, family, and for work. But in the end those small groups will overlap with other circle to create one circle including everyone. Let's just hope the transition to google plus happens quickly and smoothly.
