Version 6 results:
In[1]:= Sum[0, {n, Infinity}]
Out[1]= 0
In[2]:= Sum[0^n, {n, Infinity}]
Out[2]= 0
In[3]:= Sum[0^(2*n - 1), {n, Infinity}]
Out[3]= ComplexInfinity
In[4]:= Sum[0^(2*n + 1), {n, Infinity}]
Out[4]= Indeterminate
Given 2 is correct, the results from the last two seem rather unexpected.
