Having stated that the firmware in fact released last month on the 28th, Sony retracted that little piece of misinformation and slapped a "coming soon" in its place.
Sony's Eric Lempel blogged, saying, "we're improving the way the Flash Player works with the internet browser." This update only deals with Flash and PS3's Internet browser.
He adds that "in addition to being able to access more sites using Flash, you’ll be able to enjoy: - Full-screen mode playability - Live movie (using RTMP format) playability
- Full-screen mode playability
- Live movie (using RTMP format) playability
"Now it’s going to be even easier to enjoy web content on your PS3, in full-screen!" Flash support was introduced in v2.5 but it didn't have the desired effect as some just couldn't get it to work. Hopefully the PS3 can be Flashing gamers in no time now.
