Nintendo has become the first of the three platform holders to confirm involvement in next year's E3, with Microsoft and Sony yet to make a firm commitment to the reborn expo.
Speaking exclusively to GamesIndustry.biz, Nintendo UK PR manager Rob Saunders said, "I can confirm that Nintendo will be involved in the E3 expo next year."
However, details of just how big a presence Nintendo intends to have at the newly-formed event have yet to be revealed.
Microsoft's stance is less clear, with a spokesperson from the company's UK office telling GI.biz, "We're supportive of the move ESA has taken. It's still early days, and we're not in a position to talk about what Microsoft will be doing in regards to next year's E3, but we'll be making an announcement nearer the time."
A Sony spokesperson said: "We'll be making a statement about our plans for E3 in due course."
The move to reformat E3 as a much smaller event was confirmed by ESA president Doug Lowenstein earlier today.
He confirmed that next year's show — which has held the games industry in its thrall for the past 12 years - will be retitled the E3 Media Festival for 2007, and is slated to take place in July as opposed to the traditional May timing.
However, as the cross-spectrum first reactions from the platform holders show, the impact to the entire industry of losing the event is still unclear. Greater clarity is expected towards the end of the week as the US arms of Nintendo, Sony and Microsoft all make their official comments regarding the move.
