Why is it hard to believe that third parties are biased against Nintendo?

1) Nintendo barely supported the Wii after 2010, and it seems to me as if third parties followed Nintendo's lead. In terms of PS3 vs. 360, Sony had a massive advantage in the Japanese market, which I believe helped the PS3 gain steam in 2008 and 2009. Valkyria Chronicles and Demon's Souls were successful internationally.

2) Not sure if moneyhatting or bad business decision.

1) Why would Third parties follow Nintendo's lead? Wouldn't less 1st party games make for a more appealing release window for 3rd parties?

In a less extreme situation, I believe that would apply. However, the shift to 3DS and overall lack of major Wii releases in 2011 suggested that Wii was on its last legs and would soon be replaced.
