The delay of titles like Socom and Resistance is entirely unrelated to their inclusion of Move. Socom was in all likelihood simply not ready to be released, considering it was announced well under a year before its intended ship date, and was announced before Zipper had even managed to ship MAG. People were shocked to think Zipper could possibly ship two games in under a year, and the delay wasn't very surprising to most.
Resistance 3, on the other hand, hasn't been delayed at all. When Insomniac announced their deal with EA to go multiplatform, they claimed they did so to facilitate three year dev cycles for future titles instead of just two. Resistance 3 is the first game to benefit from this, which explains the year delay. This isn't very surprising after the complaints that Resistance 2 felt rushed.
Plus neither of these titles will require Move. Both are merely intended to tempt hardcore gamers with the thought of playing such titles with Move. And that's even assuming Resistance 3 will support Move, something that is by no means a guarantee.
I honestly don't think Sony has very big plans for Move. They're not intending to pull a Nintendo and take the casual audience by storm. Everyone knows that boat has sailed, and Move is simply there to let Sony say, "Hey look, we have motion controls too!" They hope to convince any ps3 owners looking into the Wii that they don't need it, and any non-ps3 owners looking at the Wii that they should buy a ps3 instead. That and of course sell a bunch of new expensive accessories, as well as tip the sales of more multiplat titles in their favor (Tiger Woods ps3 vs 360, for example).
