My boyfriend said he's planning a surprise for me, I'm taking bets on what it is

He usually tells me if I ask enough, we're both pretty bad with secrets like that, but he's been 100% adamant that he's not gonna tell me.
I hate surprises and figured I'd have some fun with it.
What do you think it is? We're betting with SW gifts or something else related to SW...we'll figure something out.
