They announced it as E3 sale in the CDProjekt Summer Conference.

And Amazon too actually, but my assumption had taken in those consideration based on the following:

Steam and D2D are often direct competitors when it comes to digital sales, so if Steam has it, D2D often has the sale sale as well.

For retail versions, the same goes for Gamestop and Amazon. Amazon actually has pretty good offers all year round. There are often even very good sales on pre-order items, even for their collector's editions.

My point is, any one can come up with a sale, but a sale on such a title, so soon and at such a discount, is a first on Steam. Hence my association with it on the 9GB patch.

If someone told me i would need to patch up 9gb's for every new patch after the intial 16gb download, i would just go and buy retail and get the regular size patches, Physical copies still seem to be far better.....

Yea I also bought New Vegas about 2 mos after it came out at Best Buy for $25 (They usually discount PC games quite abit anyways -store to store) It could be because Sales dropped (but its a promo!!), In America Capitalis's motives are obvious, best return for investments, law of dimishing returns and all that!!..I do think they have done well for their investment and they may be biting themselves in the foot!!

I wanted a good game ahd was hoping it would bring me as much enjoyment as The Witcher 1...it hasen't, some things are good but overall the ratings are starting to decline...the XBOX is diminshing them and I am putting them back into the INDY category,myself.

Then it begs the question, why doesn't the GOG version have the same offer, even though CDP stands to gain the most from the site? (Other sites like Steam gets a cut) I'm guessing any announcement made by CDP is merely for publicity's sake for Steam's service - after all:

1) A sale on Steam or otherwise is still a sale for CDPR, even though they may lose a bit from the sale, but potentially gain more from those Steam-only users refraining because of the patch.

2) It is their title after all, people who had issues with the size of Steam's patch complains and floods CDP's thewitcher.com site too. So it's only reasonable they try to appease potential Steam buyers since Steam's issue on the patch is also CDP's issue in a sense.

This may also account for why of all the services (Digital and Major Retail Chains), GOG which has the smallest patch file did not get the discount. Since GOG.com and hence CDP gets 100% of the purchase price, even though the same principle applies (lower cost per item coupled with higher number of buyers = greater revenue), CPR does not think that the price difference will make much of a difference since potential GOG users will not be turned away by the patch problem, unlike the other two platforms. (Both of which comes with DRM, even though retail can now be patched to be SecuROM less, the stigma remains. There are users on Steam forums which now refuses to buy anything with SecuROM even if it's only a disc check. They just hate its presence in the first place.)
