I voted Nay because imo SH4 at current is a buggy POS with severe playability and gaming issues. Then again, to be fair, so was SH3 when it came out, imo, which is why I didn't play it, either, until it was fixed.
Which is why I still believe SH4, once corrected, will not only outshine SH3 it will ROCK.
But until that day comes (and I fully expect it to) I'll stick with SH3 for the nonce...
