Ok, looks like my guess was 3 days off. According to Circuit City’s website, the LG BD300 will ship 10/10 and is available for pre-order at $50 less than what LG/Netflix originally announced.
In case you forget, the LG BD300 is the first Blu-ray player to include a built-in Netflix player for streaming movies and TV shows. I also found the official spec sheet and it looks like it will rock a front facing USB port allowing you to connect a hard drive or flash drive for playing back stored movies.
You can preorder it here for $350.
Update: Looks like Amazon has it for the suggested MSRP, $400, but doesn’t ship for 2-5 months.
