Actually not

According the information, the TGE4W isn't for the wiiware licensing sheme. It is already in use right now, which clearly indicates true Wii SDKs (although they only cost 1500$ as well and I don't think that TGE4W will be that significantly cheaper, not even for WiiWare licensing sheme)
As far as i know you also will need a DevKit for WiiWare. WiiWare is just good for that you get around all the licence issues.
