If these numbers are true than Bayonetta is pretty much in line with Madworld, which is quite surprising; I expected it to do much better than Madworld. It's a much bigger production and in a much more popular genre, SEGA can't be happy with those sales (It would've costed much more and was actually advertised on TV. It may have just over doubled the sales of MW with both consoles combined but it would've costed much more than double the amount it cost MW to produce)
Tatsunoko Vs Capcom is quite an eye opener, it managed to almost double the first week sales of it's japanese counterpart! (TVC was released on Jan 26th so it would've been tracked for about a week in the US) Those sales are pretty damn impressive considering that half the cast are completly unknown to most people (hell even most of the people on here, myself included, don't even know where these characters come from and that's saying something!) and that it's in a niche genre!
As for NMH2, don't count it as a bomba just yet. It's first NPD sales figures account for about half the amount of time as the original game. It may yet be able to keep up with the original game, considering the legs that Wii games tend to have! (and even considering that, it would still be SUDA's 2nd best selling game of all time anyway)
Dark Void is as big a bomba as Bionic Commando. I wouldn't be surprised if Dark Void Zero outsold it (funny considering that Bionic Commando Rearmed outsold the retail game as well, hell both downloadable games were better recieved critically as well :lol)
