Forum:I got a Question about the ending scene of Sonic Unleashed

Well greating everyone i watcht the last scene of Sonic Unleashed were chip and sonic comes flyning the sky and hits the ground again ( lol funny like it the start) but thats not the thing the thing is when sonic was goign too see for chip chip changes in a ring. Sonic takes the ring and puts it on and runs off etc. Now my questione is sonic put the ring on in a scene so that means that ring should be shown in sonic and the black knight too am i right? but if you look right he doesn't have one he just have hes normal clothe gloves shoes etc. but nothing new just the sword thats all. Should the ring be in other sonic games now or not and if yes why?

( sorry for ym bad english im german)

thx for hearing me Flammer The Hedgehog
