3rd parties are having decent success on the Wii right now-- they are finally realizing some quality games that are finding their intended target. Games likes Udraw, Monster Hunter 3, Sonic Colours, Epic Mickey, Goldeneye, CoD: Black Ops, Michael Jackson, Just Dance 2, The Sims 3, Lego Hary Potter, Cabela, and Toy Story 3 have all performed well this year.
Only a few top tier 3rd party games flopped: Red Steel 2, No More Heroes 2, Tiger Wood '11 (the onus is all on Tiger), and possibly a couple more.
Do you think 3rd parties will see this success and continue to produce some quality exclusives for 2011? The only big ones I know of so far are Lost in Shadow, Conduit 2, possibly House of the Dead Overkill 2, and possibly Dragonquest X.
My personal opinion is that the 3DS may help to spur some quality 3rd party Wii game development. There may be many cross-ports between the 2 systems. I don't know if this is a good thing or not, but I won't be too surprised if we see many dual versions of games on 3DS and Wii. We already see it to a degree between DS and Wii, but now the systems will be even more similar. The 3DS has some great 3rd party games lined up for it, hopefully some of these efforts also translate into better Wii games.
Most anticipated games of 2011:
Uncharted 3,Legend of Zelda: Skyward Sword, Rocksmith
Modern Warfare 3, Super Mario 3D
