Thanks for the heads-up Sachin. I know the EX500 has just launched. And I also know it has MotionFlow 100Hz. Was initially interested in it, but finally decided against it, as I don't think I would be needing the MotionFlow. On some US forums, there have been mixed reactions to 120Hz technology, with many people saying it introduces a "Soap-Opera" effect. Since majority of my viewing would be films (DVDs and blu-rays) and cricket (not as fast a game as football), I felt that the single extra feature was not worth the 8000 extra I would have to pay for it. Hence, decided to go in for the EX400.
EDIT: And I see you intend to add Monster cables to your set-up. If you are going to import from the US, or if you have a relative coming down, you should seriously consider Monoprice cables instead of Monster's. Monoprice have very good quality cables and are quite cheap compared to the overpriced Monster. Check AVSForum, and almost everyone there recommends monoprice cables. BTW, they have expedited shipping to India too. You could try that, and see if it works out cheaper and better.
