Naughty Dog has two teams now. One team was working on the Last of Us and another on Uncharted 3. One team is probably working on Uncharted 4 now - or maybe both are to produce it as quickly as possible.

3rd tweet.

Look at the capital letters in weird positions...

We never can really know what truly is going on at Naughty Dog. However I think Sony is investing in the studio and by using an upgraded engine based upon their current they can release games faster. Perhaps they have already 3 teams (2 core and one smaller).

I am thrilling to see either Ucharted 4 or TLOU2 (too early so don't get hopes up). But why not Savage Starlight. They have a story, they have a world and it can be an interesting game.

Please be Uncharted 4.

What if they buy Crash's right back after it's success on PSN and try to attract younger gamers again on PS4 (+ nostalics) ?

Ohhhhh I see I didn't even notice that the first time I read it lol. Thanks for pointing that out. 

They have two teams.

The team that produced U3 has been working since 2011 on a new project 

They have 2 teams in the studio

Yes they can. Sony split Naughty Dog up into two teams.

One did TLOU right? The other one should be working on UC4. They can't go long without their hit series hitting ps4. I just can't see them making two new IPs back to back.
