I highly doubt you'll be able to get any playstation 3 or nintendo wii bulk orders for at least a while.
Thing is, Sony can't even keep up with demand, and probably wont until March of 07, which then they will have to satisfy the european market.
Considering that nintendo will most likely hit their 4 million mark by year end, you will have a better chance of getting a wii bulk before a playstation 3 bulk order.
Sorry, but i hope this answers your question.
