Samsung announced the new 7-inch Galaxy Tab 3 tablet this morning, but unsurprisingly it won’t be the last slate the Korean company launches during 2013. In fact, according to a leaked tablet roadmap, we can expect at least another three Galaxy Tab devices — all in different sizes — plus a new, eight-core Nexus 11.

The roadmap was obtained by SamMobile, so it’s certainly not official, but this site has a very good track record when it comes to Samsung rumors. Take the following details with a pinch of salt for now, then, but note that it’s probably the the most reliable pre-release information you’ll see.

According to SamMobile’s source, we can expect at least four additional tablets from Samsung this year, all of which look very interesting.

The smallest of the bunch, the Galaxy Tab DUOS 7.0, will reportedly offer a dual-SIM card slot— something we don’t usually see in a tablet; while the largest will be a new Nexus 11 for Google that will become the world’s first tablet with an eight-core processor.

Here’s the full lineup, according to SamMobile:

Samsung Galaxy Tab DUOS 7.0
– 7.0” PLS LCD 600 x 1024
– 3 Megapixel (back)
– 2 Megapixel (front)
– Dual-core
– DUAL SIM
– Micro SD 32 GB

Samsung Galaxy Tab 8.0
– 8.0” AMOLED 1080p
– 5 Megapixel
– 2 Megapixel
– Quad-core A9 (Exynos 4412)
– Micro SD 64 GB
* Samsung need to solve AMOLED burning problem first.

Samsung Galaxy Tab 11
– 11” Super PLS TFT
– 8 Megapixel
– 2 Megapixel
– Dual-Core A15 (Exynos 5250)
– Micro SD 64 GB

NEXUS 11*
– 11” Super PLS TFT
– 8 Megapixel
– 2 Megapixel
– Octa-Core A15 / A7 (Exynos 5410)
– Micro SD 64 GB (Rumoured)
* Needs to get approvement from Google (Worlds first Octa-Core tablet)

Again, all of these devices look like they’re worth getting excited about, the Nexus 11 in particular. If those specifications are accurate, and the slate is priced as nicely as other Nexus devices, then Google could launch the tablet to rule all Android tablets.

For those who like something a little smaller, the Galaxy Tab 8.0 could also be a winner.

SamMobile also reports that Samsung may cancel its next-generation Galaxy Note 10.1 tablet due to the disappointing demand its seen for the original.
