There will always be a cross over (though Wii was probably less so in this respect?). With a combined console sales of over 100 million between sony/ms, its too big of a market to ignore initially.
Its just whether companies will have a combined game that runs on both or were talking more about download games..or reduced normal releases. just dont know yet. But i dont expect it to be dead over the Christmas period or the first 3 months of the year, with both companies and 3rd parties, there is always a chance of something being released (including DLC etc).
The PS3/Xbox will initially have an impact on sales for next gen consoles, but I feel the really big new releases will really give gamers a reason to buy...
One thing is for certain, its going to be an interesting year :)
