HDTV sales seem good AFAIK. I don't trust Pachter's opinions, he has been wrong too many times.
The PS3 is hurting from cheap 360 entry pricing (119 Euro including 19% taxes around here) and English-media anti-Sony hysteria, it makes the console look more expensive and its future more uncertain.
I think a cheaper slimline PS3 and an amazing 2009 line-up will turn things around.
