Hi. I work for a video game store and "Contra 4" for DS just showed up
in my POS today. Is this real?

Retailers seem to get the scoop before we do...love the sales teams at
game publishers breaking the news before the marketing can. Konami
hasn't officially announced any update to Contra on the Nintendo
DS...but we've certainly heard rumblings that a dual-screen rendition
(and not the arcade emulation version in Konami Arcade Hits) is being
considered. When we know more, we'll let you know.
