A retailer in Belgium has already listed Core i5 and Core i7 Haswell configurations of the unannounced new Mac mini.
Apple updated its entire Mac lineup in 2013, except for the Mac mini. The MacBook Pro, MacBook Air and iMac models were refreshed with the latest Intel Haswell processors, whereas the Mac Pro received a complete makeover, including radical changes to its design. Apple is yet to mention the Mac mini, it didn’t reveal any plans pertaining to this particular Mac in 2013, so right now its not known for sure if and when the company is going to release the refreshed lineup.
Though if the retailer is to be believed, that might happen as soon as next month. It is claimed that the new lineup is going to be released by the end of February, the retailer claims to have received this information from “reliable sources.” Retailers did see inventory tighten up towards the end of last year, which led to rumors about the upcoming launch of a refreshed lineup. It is also believed that Apple has carefully managed the Mac mini’s supply, only because it does not want the market to be flooded by inventory which ends up collecting dust in warehouses. Usually though, tight supply is often taken as a sign of an oncoming successor.
Apple never comments on speculation or rumors, so its highly unlikely that it will make an exception for the Mac mini and reveal before time what its plans are. If it intends to release the Haswell Mac mini lineup next month, then it most certainly will without prior notice.
