They aren't hiding it. It's available right now on the PC beta with the Caspian Border map.

exactly my point my friend, exactly my point

Then I don't understand your point. You say they're hiding it but you can play it since yesterday on PC.

was just horrendous marketing on EA's part. A significant number of the beta players won't come on sites like this and read the articles about how old the build is, and despite the in-game message stating 'beta is not representative of final product' the game is less than a month from launch so many will question what changes will be made. Although Rush is more applicable to the stragety of Battlefield games, many people preffer the 'run-and-gun' tactics assciated with Team Deathmatch, again hindering the betas recpetion. This is worsened as many people will be unfamiliar with the Battlefield series as this first impression will put them off, and instead opt for the familarity of Call of Duty.

Personally, I was frustrated with the beta and this caused me to cancel my pre-order. Knowing my habit, it is quite possible I end up pre-ordering it again later on but right now I'm waiting to read the post-release reviews before I decide whether to get it in the end. If not, then it will have thrown my holiday purchases up in the air, as Battlefield was the reason I cancelled my Gears of War pre-order.
