Which is?
Ratchet Gladiator is the European name for Ratchet Deadlocked (The PS2 'spin off'). America has been enjoying the remastered game for 4 months now (Free if you bought Ratchet and Clank Full Frontal Assault) but it was too buggy for SCEE so it has been held back and the bugs worked on.
If you are asking for more detail on 'Very soon' just throw a dart at a calendar on October would be my guess.
