I am new to this and am really thinking of splurging on a Granite or Vorteks. Both seem to be amazing. But I saw a reddit thread that thought there may be redesigns for the 3s lineup coming out soon. I don't want to buy one and then see a better version come out a month or two later. It's a big investment, and I don't want to regret it. Does anyone think any new models are on the horizon? I appreciate any thoughts.
