New gMail in the Works

According to this CNet Article, there might be a new gMail in the works. Well at least a new (and improved?) interface that might support Gears.
Personally, I basically always liked the interface as is. It provides a simple and convenient way to access view and access the e-mail. Gears might be useful but if I usually want offline support, I'll use a standard e-mail client like Thunderbird.
Knowing Google though I am sure that it will be a considerably better version! I hope that they spend sometime putting in some improved mobility aspects. Some of things I would like to see include:

• SMS push notifications
  
• and or direct push of e-mail to mobile
• Better mobile client
