These are just some quotes from reading that stood out to me, give the full article a read.
"Levine writes that Valve plans to include both "casual and competitive games modes" in Counter-Strike: Global Offensive with dedicated servers and a built-in matchmaking system. The first CS GO map that the small group of Counter-Strike enthusiasts played was the iconic "de_dust," which game designer Jess Cliffe reportedly said was being "overhauled to become competitively played.""
"Veiser tweeted that the game was apparently "based on the Portal 2 Source engine.""
""We got to play dust, dust2, inferno, and nuke," Levine writes, confirming the existence of the series' best known maps. Valve reportedly also confirmed that "de_train" would be included in Global Offensive's map rotation among other unspecified maps."
"The next Counter-Strike will also reportedly add some new weapons to its arsenal, including a "new heavy machine gun rifle, new pistols, and a new shotgun." Valve is also experimenting with two new grenade options, a pricey Molotov cocktail—designed to block rushes and do area of effect damage—and a decoy grenade that emits gunfire sounds intended to confuse players who rely on audio cues to determine player positioning."
"Levine also touched on the gameplay nuances of CS GO in his write-up, ... , saying "pro players seemed surprisingly happy with the player player movement and feel of the game.""
"Valve is also reportedly experimenting with weapons that have "situational value." Instead of players committing solely to the strongest, most reliable options—the AWP, Desert Eagle, AK-47 and M4A1—it appears that the game's developers intend to make sub machine guns, shotguns and pistols viable purchases."
"according to Veiser, Valve may be planning a closed, invite-only beta test for Counter-Strike: Global Offensive in the coming months. Attendees of this month's PAX Prime and the Eurogamer Expo (late September) will have a chance to go hands on with the game"
More or less one or two things a paragraph but the full read is nice. Seems like a lot of love in the project and Valve inviting the pro's from CS:S and 1.6 to play it is a nice touch on things.
