Found the following info on http://www.tofugu.com/learn-japanese/. No idea whether all three parts will be available at once, or if he’s going to do one at a time.

EtoEto: Fugu

This is part 1 of EtoEto, the new version of TextFugu. This part is the updated version of TextFugu, which will teach the basics of Japanese, as well as get you ready for part 2 (see below: “EtoEto: Kappa”). It will have new content, updated content, quizzes, Q&A, and much more when it is released in 2015.

EtoEto: Kappa

Kappa is part 2 of 3 in the “EtoEto trilogy.” It will contain intermediate contents, and span the gap between beginner and advanced. A lot of Japanese learners get stuck at this “plateau” and don’t know how to escape, but Kappa will help you to do that while teaching you intermediate Japanese grammar. Coming in 2015.

EtoEto: Kuma

Part three of the EtoEto trilogy… this section’s purpose is to get you to Japanese fluency, and to make you sound good while doing it. The main focus is on language shadowing, and there is a lot of content, audio, and lessons that you can use to do just that. Available early 2015.

Website: Coming Soon

One thing I wonder is just, how much do you think the current version of TF covers of the upcoming EtoEto Fugu? It won’t take a long time before I’ve finished TF do you think It’ll be possible easily to jump into EtoEto when it gets released?
I really hope so.

According to an email I received on wanikani, lifetime textfugu members will be getting access to etoeto in early 2015.

But honestly, I’m more than happy (but I’m likely in the minority on this) to wait as I have more than enough to study between this, genki, wanikani, iknow, and tae kim. I need to quit my job to study all the content I currently have.
