Let's also put a little perspective here.
When TW2 came out CDPR was pretty much an unknown company. If in early 2011 you asked people who CD Projekt RED was, they'd have no clue. TW2 has put CDPR into the mainstream of gaming. I won't say to the level of other franchises, but most gamers and especially those who play RPGs know them. Right now they are also highly regarded in the gaming world. So of course there's going to be a lot anticipation for their next game.
On another note, the gameplay should be interesting to see. This will be CDPR's first venture into a shooting type game.
