"Following the strong showing of Assassin's Creed at E3 and the current buzz, we now think the game should be selling around 15 per cent more units than the first title," stated Alain Corre, executive director for Ubisoft, in a conference call yesterday. 

"Our previous guidance suggested it was going to sell less units than the first title. Most of this performance actually comes from the addition of one platform, the PSP, of which Assassin's Creed was not released in the past. Half of this performance is done with guaranteed bundles," he added.

That's a bit optimistic, but possible.

I think it's easily doable, especially with 'guaranteed bundles'. Good deal for both UBI and Sony.

i would say it's more like the other way - Assassins Creed 2 will move 15% more sales of Assassins Creed Bloodlines.

Well, if the first one did around 10mln(with PC) so, he reckons that PSP alone will have 1,5mln sales LTD? Optimistic, if you ask me...

Make a PSP Game to expand the audience of the series so the HD version could sell better?

Doesn't sound crazy, maybe a little optimistic but it does make some sense.

I wonder if SEGA's taking a similar approach with Valkyria Chronicles.

Well, the PSP does have a larger userbase than PS3 or 360.......

Yeah, i hope it happens.

It will happen... and half of that will be bundled... I wonder how many bundled copies will be out there. 200k?300k?500k?
