This was not unexpected however I think this will backfire on them especially given the short one month notice. My guess is that a lot of companies will just NOT bother migrating to Gree and just pull the plug on them altogether. With most apps supporting both Gamecenter and OpenFeint I see zero incentive to spend the time migrating to Gree.
It’s a bad situation any way you slice it, and while GREE is offering a solution to migrate developers to their new platform, with how they’ve handled the OpenFeint shutdown the general consensus amongst developers on my Twitter feed is that playing ball with GREE is the last thing they’re interested in doing.
