I wonder if they're trying to say:
"a 2d Castlevania for the Wii and DS, plus a 3d one for the 360 and PS3"
or
"a new Castlevania for the Wii and DS, plus some 3d game for the 360 and PS3"
In any case, I'm moderately optimistic. I liked some of the older Castlevanias, but the series was one of those that didn't do too well in the jump to 3d. Going back to its roots on the DS seems to have worked well enough, so a 2d console version would be quite logical.
