I was reading on xda forum and someone over there supposidly got the dk28 froyo update and has a screen shot of it. I havent got anything but om rooted so I dont know if the guy is trolling or what. Its under android development over there.
Good lookin' out - it appears dev units are getting OTA Froyo updates. Not sure when this will be pushed to the public. Build is indeed DK28. Someone on XDA is getting a system dump of the update, and I will post it in ROMs/Hacks as soon as it becomes available. If this is an OTA update I'm assuming it's an official build, but I don't see any confirmation of this yet. If anyone wants to read through the 175 posts and try and find more info, you can do so here.
