Flat rate GPRS/WCDMA

Everyone looking for a flat rate GPRS tariff plan is probably interested in BASE Germany’s recently launched GPRS/WCDMA flat rate tariff called Internet-flatrate. I’m sure this will drive mobile data usage. For €50 per month you can eat all data you want, and make unlimited on-net voice calls. That’s a €25 premium over their voice-only flat rate tariff. The terms of the service exclude VoIP, voice mail and WCDMA video calls.
Will this be offered by BASE Belgium as well, in analogy with the voice-only flat rate?
