They're redesigning the game, that won't be done quickly. They already stated they won't introduce content till they get the foundation fixed. Increase sizes = better display of detail which is basically adding in groundwork for the future, as they again mentioned. It takes longer to redesign a game than it does to create one initially.

They aren't investigating how to implement jump/an AH, they're investigating if it's even worthwhile to implement. The Market Ward search is the same basic search system AHs uses.

Since you feel you can come up with an AH schematics in less than a day, create the outline, create the code, setup a server and give us access to a virtual one so we can play with it to see how a "day's work" pan out.
