The screenshots from a Dutch site SegaOnline that depict the "Sega Vintage Collection" for the Xbox LIVE Arcade are proven to be fake. What gave it away was written at the bottom:
"SEGA. ALL THE RIGHTS MOVE."
What the heck does that mean?! Kotaku contacted Sega, who replied, "Nope they didn't come from us, that's for sure. Thanks for checking." There you have it. These screens are apparently fake, not from Sega, and this rumor is smashed.
