It's a bad translation, he's basically saying the new game has the same conceptual roots as Ikaruga while being a totally different sort of game.
The update doesn't really give anything away that hasn't already been disclosed: in essence, the game system is there but M2 doesn't have an in-house team that can do it justice, so they're still considering whether to work with external contractors, hire more people, etc to bring the graphics up to scratch.
Ah, that makes sense. I originally thought 'ooh, side-scroller' then laughed at myself for being so stupid and getting 90/180 mixed up.
