Borderlands has no chance to reach 400k first week, it is just a port.
Bloodborne will reach 250k first week alone in Japan and in the west it could easily reach 300k first week. lol

"I say:  FW  BL - 400K,  BB - 250K"

Seriously, wtf?? Bloodborne can do close to that in Japan alone

Bloodborne is a niche title and it will probably have low numbers but I'm not going so far as to overestimate BL's popularity.I think the FW win will definitely go to BB. BL2 might beat it LT.

I was only looking at PS3 sales, BL doubles what DS sells. Maybe one of us is looking at something different.

Anyway, I believe that Borderlands is a game that appeals to a wider variety of gamers, while Bloodborne is aimed at a very limited target audience (hence niche). It will not sell well, no matter what gaming forums say, because hardly anybody outside gaming forums will venture to buy it. It simply looks uninviting and unmarketable. 

As for Japan, if PS3 version of DS2 barely managed to sell 350K to date on 10 million consoles, I find it ridiculous to believe Bloodborne can do 250K+ first week on a million consoles (this part not aimed directly at you, but on predictors in this thread). It should be considered a major success if it tops 100K.

So, you believe that a sequel to games that did about 500K and 350K lifetime on 8-9 times the install base can do that kind of numbers in first week on PS4. We can even see that the interest for the game is in decline.

I think many people here overestimate Bloodborne. A lot.

Don't think it will outsell bloodborne on PS4 but good shout in bringing attention to the fact that this game is very different from most ports.

A lot of people skipped the original release because it was launched on dead last gen consoles (Just look at AC Rogue for example- atrocious sales for the series), I fully expect its current gen sales to compensate from that.

@Bold: Bloodborne isn't a sequel. Demon's Souls also managed 350k lifetime way back in early 2009 in Japan only. Then it was a new entity. Now it has an established fanbase. Dark Souls II did 260k on PS3 FW in Japan only and 590k WW. Why would Bloodborne fall by a HUGE amount to 250k globally? Look at sales of exclusive PS4 software (and 3rd party software for that matter) at this point. Do you see PS4 games selling less than PS3 games despite the huge install base difference? No. Why? Because install base is not everything.

Also correct me if I'm wrong but Bloodborne should be the first AAA exclusive for PS4 that japan actually care about. That normally means inflated hype and long legs.

here are the sales i see:

demon's souls: 1.77M

dark souls: 1.97M

borderlands: 2.02M

borderlands 2: 2.10M

games that came out after the ps4 launched:

dark souls 2: 1.15M

borderlands the presequel: 0.48M

franchise totals

souls: 4.89M

borderlands: 4.60M

now it is worth noting the presequel came out 5 months after dark souls 2 and more gamers were likely to have moved onto next gen hardware but i don't see how you can make an argument that the souls franchise is niche and borderlands is popular.

you could be right, OP. normals wouldn't know a good game if it hit them over the head. just look at all the top selling games: call of duty, assassin's creed, HALO. the masses are easily led
