I don't actually know the release schedule for the PS3, except for GTA4. It should definitely sell more that week than the Wii. Once/if Nintendo ever gets supply issues under control, it'll get harder and harder to do.
Either way, it'll probably only happen on weeks of big releases, like FF13, GTA4, GT5, etc. But it won't be enough to continuously lift the PS3 over the Wii, and so it won't be enough to counter the Wii releases (which will also raise the Wii's sales), so the PS3 won't be able to reach Wii levels long term.
