From an article on Ten Ton Hammer - http://www.************.com/teso/new...tal-pre-orders
Yesterday Zenimax Online Studios revealed pre-order details and an Imperial Edition for The Elder Scrolls Online (TESO). Since that time digital retailers opened pre-orders for Standard and Imperial Edition digital versions of TESO, but Ubisoft is going that extra mile to try and convince you to purchase through its Uplay service. So if you plan to pre-order digital only, keep on reading for some juicy deals.
If you pre-order the Standard Edition ($59.99) of TESO from Uplay, you’ll not only get the 3-day headstart and pre-order items for the MMORPG, but also a copy of Assassin’s Creed III. Opting for the Imperial Edition ($79.99) will get you 5 days of headstart, an assortment of digital items on top of the pre-order bonuses, and a copy of Assassin’s Creed IV: Black Flag.
Green Man Gaming is also sending out 25% off vouchers for TESO to subsribers to its newsletter. If that interests you, you may want to sign up.
TESO is scheduled to launch for PC and Mac on April 4th, 2014.
Honestly, thought it's obviously a ploy on Ubisofts part to try to get more people to use the Uplay system, it doesn't help when it comes to what the pre-order advantages provide. Offering more on top of lore-breaking and unfair advantages given by the ninety dollar edition dose very little to endear either of them to most folks :s
