I don't want to throw a kink in your choice of TV's but Panasonic makes a 50 inch G25 plasma thats better than the S2 has vieracast which means it has built in netflix, pandora ect...
http://www.amazon.com/Panasonic-VIER...7105044&sr=8-1 of course you will still need a bluray player. If you are dead set on the S2 i'd suggest the Sony S570
http://www.amazon.com/Sony-BDP-S570-...23&sr=8-1which has built in wifi. If you go with the G25 TV you can buy a cheaper bly ray player like the Sony S370
http://www.amazon.com/Sony-BDP-S370-...7105947&sr=8-1 which is a great player without wifi. If I can help you feel free to PM me. Also head over to the AVS forum you can find a thread on the S2 and G25 and it will tell you everything about the TV's
