No, Portal is for PC only. Portal 2 is for PS3,Xbox 360,and PC. Plus it would suck on PSP.
Portal 2 comes out on April 18, 2011.
You cannot get a demo for Portal 2, and if there were it would be on Steam as Valve (the creators of Portal 2) distribute all their games there exclusively. However, if you haven't played the first Portal game I would recommend it, and if you like it you'll be sure to love Portal 2!
Poke park 2 is multiplayer but only the attractions.
Wait for Portal 2.

Yes. Go to Multiplayer and choose "Splitscreen"
only in multiplayer the robots are named p-bot and atlas
Yes, garry's mod will work with portal and you will have all the HL2 stuff.
Yes. Portal 2 supports both online and offline multiplayer.
Tetris, 2048, Bejeweled and others are all games you can find on the web. If you mean "online multiplayer", I recommend Portal 2.
It depends on your preference. Black Ops is a shooter game that has a very popular multiplayer mode online. Portal 2 is a puzzle game that is also very successful, but personally, I don't find it to have too much replay value.
Portal or Portal 2 mods on Steam is installed by first Downloading it and extracting it. Then copy the map file into your Portal 2 maps folder which is Run the game.
Yes and Portal 2.
