The rapper listed a new baseball cap on his official online store, which lists the years he released a solo hit album.
However, the list of dates ends with 2013, suggesting that the star's eighth studio record will land next year.
The baseball cap - named the Eminem Baseball Tribute Champ Hat - is described as being sold "in honour of the big games and the hometown team's return to The D".
The side of the cap sees embroidered text, which the description explains is "dedicated to the landmark Eminem solo albums".
The new collection will serve as the follow-up to 2010's Recovery, which topped the UK chart and US Billboard 200.
Eminem recently teamed up with Pink for new cut 'Here Comes the Weekend', which features on her latest album The Truth About Love.
