That sounds right. Especially given the rumor that Apple is cooking up their own mobile payment service.
I guess when you try to do something like this, the lawyers and other higher ups need to figure a lot of things out first. And this bitcoin business looks like it falls somewhere either within this scope or at least very very close to it.
I think they needed this time to get a comprehensive look what they were planning re: mobile payments and how bitcoin dealing might be affected by this.
