While this isn't a solemn vow each will make goodies for Home at all, Sony hopes they'll put the time in. EA has already started investing with it by unveiling their Sports Complex.
Capcom plans some cross-over content as well, most recently announcing a lounge area resembling a level from Resident Evil 5 and themed costumes from Street Fighter IV.
Below is Sony's list of license holders for Home, which includes a number of independent Japanese developers and not just big house publishers:
Acquire Activision AQ Interactive Atlus Capcom D3 Publisher Disney Interactive EA Game Republic Genki Gungho Hudson Irem Koei Konami Namco Bandai Nippon Ichi Paon Q Entertainment Sega SNK Playmore Spike Tecmo Ubisoft
