Samsung to introduce the GT-B9150 with EXYNOS 5250 processor soon

Samsung will introduce a new GALAXY product soon.
The Samsung GT-B9150 showed up on a couple of Japanese websites. The Japanese blogs are talking about a Android 4.1.1 based device that uses the EXYNOS 5250 1.7 GHz Dual Core processor, Wi-Fi and a HD resolution (1280 x 672) screen.
One of the biggest question would be what kind of device is the Samsung GT-B9150? Samsung mostly use the B series for hardware QWERTY Android based devices.

Is this finally the Samsung Galaxy Q? Or just a new upcoming tablet?
