I too want to buy one as it is super VFM gaming machine, however I think that whoever wants to purchase should wait for another three or four months.
As the Mrp of the PS2 has been reduced to 7k, the grey market dealers will be trying to sell the old stock at the same grey price which was also around 7k, they will try to justify the price saying that the original wont play pirated discs and that they original discs are expensive and start from Rs. 500 !
After the sell out the old stock, they should start selling the PS2 at 4K, though all the above is my inference if any member knows the grey market dynamics they can post some info here and help us out.
