The coding is underway.  May take a few weeks, though.  Here's the list I put togther from this thread (I includined things I like the look of and though were feasible):
1) A list of upcoming products sorted by date. 
2) Breakdowns of products by 'type' - adventure, rulebook etc. 
3) Replace the top ten lists with a single top twenty list? Add a top ten publisher list? 
4) Initial screen for each publisher more reminiscent of the current d20 Guide than the current Reviews page. One page per publisher, click on products for more detailed info, image, reviews etc. 
 
5) For the authors of a review to be e-mailed when they get a comment. 
 
6) Las 10 -- or last 20 -- products released (or last two months, whatever).
 
7) Rework the overall rating calculation (somehow).
 
8) Ability to give half a score, like 3.5 instead of having to pick either a 3 or 4. 
 
9) Colour coding or some other visual aid to indicate when an item is... available, not yet published but has a set release date, cancelled, out of print, is not available and has no set release date, comes out periodically (like a magazine, etc.), overdue. 
10) Author info for each product.
 
11) Link to buy product at the online store.
 
12) Something to eliminate 4-line reviews.  A mimimum word count, or a 'rate this review' feature?
Note that not all of these will necessarily make it, but that's what we're aiming for.
