They're talking about (cough) "semi-legally obtained" copies of PES which we can allude to here, but not discuss in detail. Cos it's against da law.
So it IS a beta then!(I haven't played it......too law-abiding, and not well-connected enough, grrr). Out of date squads and Adidas ads are the giveaway...Konami have said quite explicitly that the squads in the final PES2 will be up-to-date as of the recent transfer window, and we know the European version is sponsored by Umbro (the demo has Umbro branding, an Umbro ball etc., so if your PES2 doesn't have these, it ain't the final).
Sounds like this is just a conversion of one of the WE6s, which hasn't been polished yet. Thing is, the Umbro stuff and the squad rosters would be the last things they'd do, so it's possible that this is the final game, just with unfinished data... rest assured, the final PES2 WILL have up-to-date squads... PES was up-to-date to 3 weeks previous to release, and this year they have the transfer window system, so there's no excuse not to make it completely accurate.
The question is, does this mean that in the final PES you CAN transfer players between club sides with the edit mode? And will there be 10 custom teams in the final version? Cos if there will, that means I can fulfill my dream of creating the European leagues on different memory cards. And if there won't, that means a lot of people who get PES2 at Christmas are gonna be pretty pissed off when the next transfer window opens, everyone moves clubs, and suddenly the game is completely out of date.
