Nikon D90 DSLR demo unit recall tips incoming replacement

Rumors of a replacement for Nikon's D90 DSLR have been fuelled by reports that the company is requesting the return of retail demo units.  According to Nikon Rumors, employees at a major retailer are reporting that "all stores have been told to remove demo Nikon D90 bodies from display and send them back to head office," while others claim the Nikon SB-600 flash is also up for replacement at Photokina 2010.

Details of the D90's replacement are scant at present, though previous rumors pegged the upcoming DSLR as potentially supporting 39 autofocus points and having a 16-megapixel sensor.  It would also get 6400 ISO support and HI2, the ability to record 1080p 24fps HD video and compatibility with a new, optional MD-B11 grip.  Photokina 2010 kicks off in September this year.
