How would that be a question for this forum then?
Well, it mostly ties into Sony's choice to use the PS3 to usher in their new format, and if it was a wise choice. Sure, it's not entirely gaming related, but the discussion stemmed from the NPD threads, which IMO are just as useless and pointless to each and every one of us as gamers, but we still eat that up without question, don't we?
If Sony would have opted out of Blu-Ray in PS3, the format would have had to price match HD DVD to succeed as a format. This would have lost Sony FAR MORE MONEY than putting it in the PS3.
Additionally, the PS3 has more 'streams of revenue' than Blu-Ray players on their own, which enables Sony to sell the system at a loss, while making some money back in different arenas, minimizing their losses (movies, rentals, PSN Store, and PS3 software).
It was the right choice to make as far as ushering in Blu-Ray as the defacto HD standard. It may have not been the BEST choice for the Console wars, but ultimately, Blu-Ray may pay off more for Sony in the long run (if / when the economy recovers). Blu-Ray may help stimulate HDTV sales, PS3 Sales, Stand Alone sales, etc, which will generate revenue for the company as a whole.
