Rather interestingly, Electricpig has spotted that Microsoft has pushed its press conference back to 6.25pm from 6.30pm (GMT), giving an extra five minutes for what it's describing as a "special addition".
What an extra five minutes will allow for, we aren't too sure, but it's no doubt an attempt to bring the focus back on to Microsoft, rather than that pesky PSP Go that "leaked" yesterday.
The Big M is set to open the show today, and will be the first of the week to unveil the things it has up its sleeve for the forthcoming year and beyond.
Stuff.tv's Joe is over there and will be ready to get hands on with all the hot new kit over the next week – so be sure to keep an eye on the blog, as well as our Watch and Listen page for the latest.
In the meantime, check out our E3 rumour round up for what we're hoping to be announced, and let us know what you're looking forward to below.
