What I'm hoping that the they carry on with the plan to complete the trilogy. One of the reasons people hated so QoS so much is they didn't realize it was part 2 of a trilogy. So hopefuly they'll be able to complete the storyline, explain who Quantum is, introduce the new Blofeld (you know it's coming) and put the final bits of the Bond puzzle in place - Q and Moneypenny.
I'm not a fan of bringing Moneypenny and Q back into the picture, but if it can be done well and in connection to the larger whole, then go for it.
Other than that - HUZZAH! I can't wait.
