Halo fans can breath a sigh of relief. Geoff Keighley – host of Spike TV - has officially confirmed that Halo 4 campaign gameplay will be shown at this year’s E3:
"Halo 4 is a big focus for Xbox. We've announced that you'll see the first real campaign gameplay in the Xbox press conference on June 4. And then that night, in our primetime special we will be showing off Spartan Ops mode for the first time. I was at 343 last week. We'll be sharing more about Halo at E3 soon".
