More or less all the major announcements have been made at the first day by the developers at E3. On second day, Japanese developer/publisher Capcom looked like talking on behalf of Sony as it announced that Sony is likely to cut down PS3 price again.
Another PS3 price-cut
It's just about a week back when the PS3 price-cut became official and seems like it isn't enough for Capcom, and hence it's anticipating yet another price-cut. The developer says that Sony will bring second PS3 price-cut before 2007 ends.
However, Sony hasn't responded yet to Capcom's proclamation, we would like to hear it before E3 ends.
PS3 Getting Rumble in September
The rumble patent-holding company Immersion has given a confirmation of the Rumble feature to the PS3 controller. The press release cites that they have begun licensing their technology to third-party peripheral creators Hori and Katana to produce accessories with rumble on consoles and handhelds. Katana will be developing SIXAXIS rumble controllers for the PS3, starting in September.
Sony is tightlipped this time as well; even (Sony's) press release doesn't contain any such content that confirms a rumble-enhanced Sixaxis controller. Nevertheless, Immersion has announced it officially, something should be coming for sure by this September.
Microsoft denies Xbox360 price-cut
Looking at steady sales of Xbox360 consoles, speculations of Xbox360 price-cut have started surfacing. But, Microsoft officials have said that they will hold firm on pricing for its Xbox360, i.e. they are not pondering an immediate Xbox360 price-cut. The announcement has axed all the speculations regarding Xbox360 price-cut, so this year is not brining you an Xbox360 bargain.
Update: Talking to Bloomberg, Microsoft Game Studios' VP 'Shane Kim' has confirmed a price-cut for the Xbox360. Kim declined to mention the date and degree of price-cut.
Since, all the announcements were made on the very first day, Nintendo's booth looked quite deserted. To bridge the gap, Nyko comes with a couple of new accessories intended for Wii PS3, and Xbox360.
Nyko's Wii Party Station
First, when you throw a look at the Wii accessory, you won't find it more than a chip-holding tray, but as per Nyko, the station also comprises LCD scoreboards, Wii-mote holder, a drawer for Nunchuck, a fan, four freezing soda cup holders (with built-in gels to maintain coldness), and a chip holder.

The accessory that Nyko displayed is a prototype, but they have planned to get it real in next two or three months.

This one is also a prototype that is under consideration, and Nyko is not very sure about its launch.

The new controller resembles the original SIXAXIS in small degree like design, 6-directional motion sensing, and a removable battery pack for external charging.
Nyko Wii Cooler

The new Wii cooler is an external attachment that is attached to the back of the Wii. The cooler comes with an added fan for extra cooling that extracts some power from the Wii.
