Broadway Shows in June 2010!!!

Hi. I am new to this board and to broadwayworld.com. I am in the UK but will be coming to NYC for a week from 21st June - 28th June 2010 with my partner!! Could anyone tell me what shows will be opening before then and which ones already there would be worth seeing? I've already booked Wicked tickets because my boyfriend is a huge fan of the London production but unlike me has never been to Broadway. Are there some shows I should pre-book before I come or would it be worth waiting till I am there to get them cheaper?? Any advice would be great guys! Mark from the UK :)
