Not surprised to be honest.

Crash Bandicoot game first :P

Not the worst thing in the world unless Sony fires people for ND which I doubt

This shouldn't be surprisng to anyone. We havent even seen gameplay for the game yet and Naughty Dog has been silent about it ever sense its announcment. I expect an early to mid 2015 release which is fine.

I don't think it will too, but let's wait until E3.

I always thought Uncharted would come in 2015 since the teaser shown last year was only that, a teaser. No characters, no concrete settings, vague exposition... My thoughts are that Naughty Dog will start with UC4 after releasing TLOU: Left Behind and a break. I mean, who would want a rushed Uncharted game?

I expect it to be shown at E3 this year and come out sometime in 2015. Whole new system expected extra development time.

They're a 2 game studio, I still think 2014 makes the most sense

But that seems to be some fairly compelling evidence

I'm pretty sure Uncharted will release in March 2015 but you need to read the link too...

"we’ll keep adding to it as more games are announced"

This list is not all games for 2014.
