India in New Zealand 2009
India face a gruelling schedule during their tour to New Zealand next year, with a possible 19 days of cricket to be played in a span of 33 days.
The tour, India's first of New Zealand since 2002-03, begins with a Twenty20 international at the Westpac Stadium in Wellington and ends with the final Test, from April 3-7, at the Basin Reserve in the same city. India will play one Twenty20 international, five day-night ODIs, a warm-up three-day game, and two Tests during their trip; they return home in time for the second edition of the Indian Premier League.

India last time really had torrid time,now as mentioned in article they have to face NZ,IPL,Pak full tour, it will be very difficult, because of diffrent cilmatic onditions also, IPL runs for around 40-45 days, and Pak tour,will be very hot and exausting,like this IPL was.
Indian players dont have any option,they are controlled by BCCI.
