It's irrelevant if it will or won't have a single player campaign.
Titanfall was tremendously hyped because of its Microsoft exclusivity, MS tried to make it the next big multiplayer leader. But judging by its performance, it will become a mediocre series and just an average seller. It had a huge potential, but it will not come close to the caliber of CoD, Halo, Destiny or even Battlefield and Gears of War. It will probably fall into the category with Medal of Honor and Resistance, with a few sequels, diminishing returns and abandonement after part 3 or 4.

The game did decent, but not more than decent, without any shooter competition this spring, part 2 will get demolished in sales by those strong competitors.

What the sequel needs, more than anything else, is more depth to it's multiplayer. It's a very fun game mechanics wise and all, but it lacks modes, customisation, and diverse weaponry (or perhaps I should say effective diverse weaponry)

Is ea we are talking about remember?

At first I thought you ment an marketing campaign.

Exclusive single player mode on PS4 confirmed ?

You thought wrong. MS bought exclusivity for the first game only, they don't own any part of the IP.

I assume EA will back TF2 but it will have to be properly multiplatform. I don't see MS paying a big sum to keep it console exclusive given the first game didn't really do much for Xb one.

I do know someone who bought a 360 specifically for TF, so that's +1 for last gen.

If you call amazingly well 8m.

If they don't make a single player experience they are well and truly insane. If Respawn doesn't want to do it EA can farm it out.

What they fail to realize in their arrogance is that Titanfall owes a LOT of its success as it were to having almost no competition on release. A half baked COD released many months earlier that was coded rather poorly for the XB1. This fall sees COD:AW which will deliver the future tech MP *AND * a AAA SP campaign. Destiny will come out with tremendous marketing and support from a legendary developer. Halo MCC this year with 5 coming down the pipe.

Basically TF2 will be a lame also ran if the 2nd is another title light on content title. With such immense competition and the premise no longer being fresh, TF2 could be an outright flop if they think laziness will cut the mustard.

Where is Titanfall now? The ancient crusty source engine did it no favors. The framerate was inconsistent, the tearing pathetic, and regardless of any blinded fans ideas about the subject, the 360 version was fundamentally equivalent to the XB1 version, it just wasn't anywhere near worthy of the hype.

TF2 with a great SP and MP on a true next gen optimal engine : 8-12m lifetime sales easily. Maybe higher.

TF2 with MP only and source engine : 4m or less even with PS4 sales. Reviews will be harsh, graphics will be pathetic compared to their competition, halo/destiny/cod/bf will outright crush them.

It needs to not have aim assist, it needs recoil, it needs less bots and more players, actual 60fps instead of 20-60, etc etc
It needs a lot of things and the lack of a campaign are the least of its problems

I think a game like Titanfall with a strong multi- and singleplayer would sell better as with only a strong single- or multiplayer but on both platforms and I don't think that sales of singleplayer games would be so much lower on Xbox if advertised the same (at least not shooter games).

What you say is that Titanfall 1 would be less successful on Playstation because of the lack of the singleplayer and I highly doubt that. Game would sell a little bit better with a singleplayer campaign but that's the case for Xbox as well and sales of the game would be probably still higher on Playstation because of the bigger userbase even without singleplayer.
