I think your right.
Google Translate did a pretty good job of mangling that page and the only date I saw on that post was the 26th, which led me to believe that's when OB3 was posted. I haven't seen any activity out of the EZ Flash team (beyond selling off their flash cart to iSmart) in far too long and was just trying to dig up anything I could find. Sosuke's site is practically desert and tumble weeds these days so I decided to hit up the Chinese forums. Just to find users there complaining that it's dead there too. I was glad to find an update (Hey, Fast6191, why haven't you posted this update here?) and thought I'd share... And complain I guess.
I had an EZ2 and when the team seemed to be ceasing support and closing shop the EZ3 came into existence and updates for the EZ2 came back along side support for the EZ3. Eventually updates for the EZ2 waned, but the EZ3 was the new baby and the EZ2 was about as perfect as that hardware would support (there isn't a GBA game I know of that won't work on it even w/o updates). Then the updates for the EZ3 followed the same pattern and then the EZ4 was released. Then the same thing happened to the EZ4 w/ the release of the EZ5. They've been a very reliable team, have made some of the best carts available, have been around longer than any other flash cart brand that exists today, etc.
But I've never seen them license or sanction a clone... Which then goes and makes their software open source... And... Well, I gues I'm worried. Are they done? Is there an EZ6 on the horizon or what? I just want to know. I've got a SCDS2 and it's a great cart w/ a great bunch of features that cause me to use it over the EZ5 from time to time, but I still prefer the EZ5 and it spends way more time in my DSi than the SCDS2. But w/ this round of silence, the release of the iSmart and other factors I'm seriously beginning to wonder about the future of the EZ Flash brand.
MB Max? Fast? WinDirt? Anyone?
