First let me say that I LOVE Wizard101, one of the most awesome games i've ever played. But I'm using a mac and the problem is my Gateway computer broke down, so I think Wizard101 can also be playable on a web browser, it's easier and doesn't take a long time to download. All you need to do is login and WALAH! You can play it. I really hope this would be made possible some day.
First off - That would be HORRIBLE! This game has graphics that few Web Browsers can easily display as Non-video files. Also, being an MMO it is much harder to incorporate 'Flash' Log-ins with their current system. If they Did make a WB version, expect to start from scratch with minimal graphics.
