I worked on the PS3 port of the God of War PSP games. For that port we didn't use a new engine or add any additional graphical features, we just straight-ported the PSP engine to PS3. The artist improved some of the models, up-rezed a bunch of textures (a lot of them automatically through photoshop scripts), and switch out the Kratos gameplay model for the hi-quality model used in cinematics. The bulk of the work involved was just programmers porting the engine bit by bit until it ran on PS3, and then coming up with ways to get all of the graphics functionality working on the PS3 GPU. A *lot* of looking at the PSP GPU docs to figure out what the hell it did when some obscure feature was enabled (texture doubling, argh!). The rest was just bug fixing (a lot of data bugs from endianness issuess), and optimization. There was also a large amount of work put into re-rendering our old cinematics in HD, so that we weren't just playing upscaled 480x272 videos.
It really depends though on the project...some remakes take things a lot further and add lots of new graphical features. But I would say most are similar to what we did, we're it's mostly a straight port.
