It seems that lately Capcom has really been pumping out the vs fighting games. Marvel vs Capcom 3, Tatsunoko vs Capcom, Street Fighter X Tekken and vice versa with Tekken X Street Fighter (I know Namco is making that one but I just thought I'd add it). Do you think after this round of vs games Capcom should stop while it's ahead or should they keep on putting their characters in vs fighting games?

2 is not too many

Capcom was exactly like that in the past, so no. They are giving their fans what they want.

Vs are great games, so no.

So that makes like 4 Vs. games coming out in the span of 3 or 4 years. That doesn't seem to bad kinda reasonable actually.
Personally I want more make Capcom vs. Sitcom stars of the 80's.  I bet my team of ALF, Guile, and Mr. Belvedere will be unstoppable.

I don't think so.  TvC was released earlier this year, MvC3 won't be released  until sometime next year, and Street Fighter X Tekken won't be released until the year after that at the earliest.

I'm excited for MvC3, but yes, I think they're beginning to make too many. Meaning there aren't too many right now, but if they stay on this path there definitely will be. And I think that's unfortunate. Capcom brought fighting games back in vogue with Street Fighter IV, and now it seems they're content to flood the market with them again and possibly relegate the genre to very niche audience again.

" Of course not, I hope it keeps going until they run out of good things to pitch themselves against and we end up with Capcom vs Digimon or Capcom vs US Presidents. Then I will say they have gone too far. "

Hell nawww. They still need to release their Darkstalkers vs Soul Calibur!

Namco is making Tekken X Street Fighter, not Capcom. You know this, yet you still act like Capcom is behind it. 
You NEED both of those games to make that crossover work. You can't just have one or the other.
 
The answer to your question is they aren't making enough DarkStalkers games.

No.

Nope, I want more "VS" games.  I still want to see Disney vs Dead or Alive.

Nope, 
 
Heck I wouldn't even be mad if they made another Capcom VS SNK.

everyone loves versus games, and coupled with the great fighting games capcom makes why not?

More fighting games = good. The community needs to grow larger.

The only one I want is Capcom X Mortal Kombat.

This is good, actually, it's been a while since we've got any vs games in regular fashion. 

Is doesn't matter how many of them there are, as long as there good, you know?
