Two of the biggest PC game releases in September both come from Electronic Arts; the Will Wright designed alien life simulation Spore and the Mythic Entertainment developed fantasy MMO Warhammer Online. Gamesindustry.biz has word that a financial analyst, Lazard Capital Markets senior VP Colin Sebastian, has given some predictions on how both games will do in the their launch month.

Sebastian has predicted that Spore will generate 2 million unit sales in the US this month (it's due to launch next week). That is a massive number for a PC game and it will be interesting to see if Spore can make those predictions. Sebastian has also stated that Warhammer Online could generate 650,000 subcriptions in its first month (it launches September 18). This would seem to be a solid number considering that the launch of Funcom's Age of Conan last May has similar sales success in its first month.
