Tough one Gerald - I just have this feeling that he will play London but on the other hand having played New York before he may pull out something special for the 2 shows in March that you'd love to see and you'll be miserable you missed it.
So, I'd say - go for it. Go to NY, have a break and enjoy the city too. If London does come up, no worries, by then you'll either have won the lottery or an elderly relative you never knew you had will have left you a huge fortune so it won't be a problem
