Here’s a thread on NeoGaf outlining this rumour in more details. The thread also quotes the questionable text from the actual 4chan post. See below:

So I’ve just been fired from Ghost games so I might as well leak this, Yes we have skipped a year with NFS games, EA was at first contemplating to shut down the franchise after many titles failed to meet expectations, now as a last ditch effort they gave us more time (and horrendous working hours) to work on the new title Underground: Need For Speed

Yes this a Sequel to the Underground series, but to make it seem new we had to reboot it, make it more modern add some of the elements of 2012’s NFS most wanted If you don’t believe me, at this year VGX we will announce the game.

We are still trying to go back to the foundation of Underground by including as many import cars as possible with a healthy amount of European cars. American and Muscle cars are sadly enough almost absent besides the 2014 Ford Mustang Boss.

The customization can be broken down to Body kits, wide bumper, spoilers, Rims, spinners and we also planned to include special parts for Drag races and drift races, you can basically customize your car for the kind of race you want to do with it, Vinyls and paints also is much more expanded than first, the appearance of your car will matter, if you put it online people can give your car style points, the more style points the more your car is worth

I also forgot to add, EA is now jumping on the whole Frame rate craze and the game will run at 60 fps on all systems although the Ps4 and Xbone version are a pain in the ass to make it run well, the trailer we will show will look slightly better than the endgame, 900p on PS4 and 720p on xbone, altough the xbone version is struggling to stay at 60 and MS is pressuring us to lower the Ps4 version to 720p too, EA will probably make that call, so if they say it runs at 1080p 60 fps, its damage control

We are still in early stages but from what i could see it does try to emulate the Old NFS feel but with some burnout things like takedowns the handling Unlocks are done through the reputation you gain in the city, the higher your rep the better the unlocks, same with cars,shops, auto lots and all are visible from the beginning “

We outsourced it to the devs that made NFS nitro on DS so I honestly don’t know what to expect, the console version were EA’s highest priority no WiiU version but a special Ios version is being made and ported to 3DS.

The original NFS Underground brought the much needed upgrade to the franchise by enabling players to customise their cars while chugging along with its hip fueled story line.

Underground was awesome the last good NFS game imo.

I would die

"MS is pressuring us to lower the Ps4 version to 720p too"

Well if this game does get announced when he says we know MS are assholes. This seems fakes though.

wow would be awesome.

Underground 2 was the last need for speed game I got on consoles. So if they did make this and it was good I may get back in the franchise.

We are still in early stages... so how do you know so many specifics??
Taking this with one tiny grain of salt right now, still I hope its true... and good.

If Microsoft bullies them to dumb it down i will not purchase. Yeah 720p vs. 900p aren't a huge deal but just because the Xb1 is slightly weaker than the PS4 doesn't mean I should pay for it, because I own a PS4.

Great news if true.

With the disappointment from The Crew and Driveclub, maybe it's smart that EA get a new game out. The arcade racer is dead at the moment, even a decent effort would be appreciated
