My friend came in the other day and started asking me loads of questions about Blu-ray because he had heard on the radio that morning that it had won the format war.
With HD-DVD dead, the interest in Blu-ray will grow, ergo the interest in the PS3 as a cheap blu-ray player will grow too.
Were some gamers on the fence, waiting for one format to win? I don't really think so. A lot of movie buffs and technophiles might have been though.
