The firmware update will also be released in conjunction with Home version 1.00, according to the post. Currently, the beta is at version 0.98. The simultaneous release of firmware 2.50 and Home 1.00 has us thinking that perhaps this could mark the beginning of the wide release of Home. Stay tuned.
Update: Since writing this article, the PS.blog has updated about the expansion of the Home beta. More invites are being sent to users right now. The continued growth of the beta adds even more weight to the possibility that the final version of Home will be available next month.
