A news article (Google translation) mentions the 3G for the tablet might still be a possibility if Jolla finds a supporting partner.

Other stuff mentioned:
- 90% of product development is in software development and the main focus is in the tablet platform (licensable to other companies)
- Jolla received 10 million euros more funding during autumn (Round B)
- Looking already for Round C, hopefully several investors (rather than one large?)
- Jolla needs more employees than the current 128 people so Round D is looming ahead

I assume the tablet platform development will also benefit Sailfish development in general i.e. Jolla Phone.
