In the recent issue of Famitsu, From Software announced a PSP port of the PlayStation 2 game Armored Core 3. The game will have some new parts and various other obligatory trinkets but none of this is all that noteworthy. What is interesting is the fact that this is an obvious means to keep the series ticking over until the next real game surfaces.
Don't get me wrong, Armored Core 3 was probably one of the best entries into the series and having that portable is brilliant but it's a cheaper cost than creating another current gen (PS3/360) release. Bear in mind that an Armored Core game has pretty much been released yearly since 1997, so whilst this fits the same release window it belies the obvious fact that another game is being made in the wings (as this is just a port).
After the Layzner-esque shift of Armored Core 4 and For Answer, the release of a more traditional game also indicates a possible return to the slower and less twitchy ground pounder gameplay that made the original series such a success.
That said, in the current economic climate, this could be a last desperate act to drum up cash before the company goes under. Though this outcome is rather unlikely as the sales of their games whilst not huge are hardly crap either, plus they've done something like this before with the series (with Formula Front, as that was a port of sorts for Nexus).
