Well blizzard stated they are planing to reduce attack speed on items with those stats for making it less significant they shoud be still good but not the only pick you can get.
So my advice is do not buy items now since 1.0.3 will be here soon and maybe for those who might wana speculate about prices and risk a little bit with some profit sell your items for better prices and rebuy them later maybe but its just a speculation.
The point was if some was planing on buying some late game attack speed items you might consider waitling after they patch 1.0.3
Items you might consider are Andariel's Vissage, Lacuni Prowlers, Boj Anglers, Snail Backon and some more i do not remember right now
Here is the statement from blizzard:
"There are two different solutions we’re considering to reduce the effectiveness of Increased Attack Speed. The first is to simply reduce the value on all the items to their desired values. In general our desire is to never change items as that makes them feel less concrete, but the upside is you would still be able to look at an item and know exactly what you are getting. The other approach is to change the formula used for attack speed aggregation so that stacking attack speed from multiple slots suffers from diminishing returns. The downside of that approach is that it introduces yet another hidden modifier on an item property (and many people dislike hidden modifiers), and complicates the already difficult decision of item gearing.
We’re currently leaning toward the first solution, to simply reduce the value on items, but we’d be interested to read people’s thoughts on the problem."
