It's "Jak & Daxter", heathen.
As much as I like the series, I think they should either remake it or retcon it like DC did with pretty much all its characters. Infinite Crisis or whatever? Not a comic guy, so if anyone could clarify, that'd be nice. Why, well as much as the story sort of makes sense, and that Jak 3 ended at a cliffhanger, the Lost Frontier pretty much killed what the series could have been for most people. I haven't played it, but it doesn't look like it expands on what Jak 3 did. Hey, I know, maybe Sanzaru could do it. Sly Cooper: Thieves in Time looks great and looks very true to the Sly Cooper franchise, but the gimmick with costumes/armor might hinder it. Still, they could continue two great franchises from the PS2, but I don't want them to be the studio who only continues games and doesn't make any new IPs besides the ones before Sly 4 and the HD collection.
Y'know what they should reboot? They should reboot DmC.
Make it so it's "dmc: DmC: Devil May Cry"; yeah, that'll learn Square Enix. Capcom's got better (poor) naming. Kidding, by the way.
Ninja Gaiden could go for a reboot. Story wasn't a strong point and with NG3, it's pretty much on the ledge of "Great, we screwed up." Gameplay went from great to good to mechanics killing it. NG to me was a hack n' slash game with a 3D fighting game system, similar to Dead or Alive (obviously because Itagaki was behind both DOA and NG), Soul Calibur, Tekken, etc. DMC/DmC is more in line as a hack n' slash with a 2D fighting system. God of War . . . I have no idea what the system could have been inspired from or based on beside other hack n' slash games.
Soul Reaver could go for a reboot too. For a game from the PS2/GC/XBOX era, it had amazing voice acting and the story is pretty interesting.
Also, sequel to Dark Cloud 2/Dark Chronicles as it was known is some regions, or reboot the franchise.
