We will indeed see less of them I think. Capcom stated in their latest release that they were not interested in exclusives. MS can pay for them and Sony has its own development studios - but you will see less of them as 2008 YTD clearly shows their is zero upside in being exclusive without a very good reason.
You might see more timed exclusives - but on most forums they get negative response so I think over time they may be affected too as no company in such a consumer focused industry wants negative responses to business moves.
Try to be reasonable... its easier than you think...
