That's because the Internet giant is choosing to livestream the online-only event, scheduled for April 14-15.
However, there appears to be an A-List of some sort still, as the Android maker noted that a "limited number of participants" will be able to attend in person at the Computer History Museum nearby the Googleplex in Mountain View, Calif.
Project Ara chief Paul Eremenko noted on his Google+ page on Wednesday that this will actually be the first of three Ara-specific events held throughout 2014, offering a glimpse at the topic roadmap:
The first of these will focus on the alpha release of the Ara Module Developers’ Kit (MDK). The MDK, which we expect to release online in early April, is a free and open platform specification and reference implementation that contains everything you need to develop an Ara module. The Developers’ Conference will consist of a detailed walk-through of existing and planned features of the Ara platform, a briefing and community feedback sessions on the alpha MDK, and an announcement of a series of prize challenges for module developers.
Project Ara first surfaced to the public eye back in October under the umbrella of Motorola Mobility as a unit for building an Android-style ecosystem for hardware.
However, Motorola splintered in a surprise deal last month as Google jettisoned the beleaguered phone brand to Lenovo for $2.91 billion.
Motorola's Advanced Tech department, which oversees Project Ara, was one of the few pieces that Google kept in its grasp.
