Even though within a week both Hasbro filed a new trademark for new Rom The Spaceknight Toys and Marvel snuck Rom into an Age of Ultron panel, seems it's all just coincidence.
Someone asked Marvel SVPP Tom Brevoort over at his Form Spring if there were any plans for Rom, with Tom responding as follows:
Not at the moment, no.
The Rom The Spaceknight comic book had a 75 issue run, outlasting its Parker Bros. robotic counterpart which failed to garnish the attention of youths across America.
Rom related characters still appear in Marvel Comics such as Brian Michael Bendis' Avengers and DnA's Annihilators.
