I'm not even remotely expecting any of these to be added...but I wouldn't put it out of the realm of possibility, especially with the lineup being delayed. But again, not expecting this at all.
The schedule (which is what I assume you are referring to) has not necessarily been delayed. While it came out May 7 last year, in previous year it typically came out May 20-something. Last year's early release was a pleasant surprise, but maybe they feel as though they shouldn't be held to that early May standard every year.
