After the announcement of the ICS-running HTC Desire C (powered by a single-core 600MHz CPU), every time the dual-core Samsung Galaxy Ace 2 came up there was someone to ask “why is the more powerful phone running Gingerbread and not Ice Cream Sandwich?”.
A leaked promo video for the Ace 2 suggests there might be some hope though. The video labels the phone “ICS upgradeable”, but neglects to mention when that might happen.
Here's the promo video in question, the money shot is at 0:14.
It’s interesting that Galaxy Ace 2 is powered by a NovaThor chipset, just like the I8530 Galaxy Beam and the Galaxy S Advance (which wasn’t on the official list of phones slated to get ICS). It’s just speculation at this point, but the chances of a 4.0 update for those two phones just went up a bit.
You might want to wait for an official confirmation, but if getting stuck with Gingerbread was your only reason for not getting a Galaxy Ace 2, you may want to go back for a second look.
