You will most definitely see more details on the product prior to the first ship dates. The guys from eve take this seriously and include the community very well into the process.
As for reviews though, the statement is that the first batch is delivered before the press and others get test units. So don't expect any official magazine/tech blog reviews prior to the first shipments.
Shipping (as stated by pauliunas) is not expensive. For EU and US the tax/VAT is included in the shipping cost which means that no further taxation is to be paid to the customs authorities. That is also the reason why the US is so much cheaper (as there is only an average tax of 6%).
Performance-wise, it should hold up to certain tasks pretty well. The turbo speed is 3.6 GHz (which is higher than the core model). If you need heavy calculations and constant high CPU speeds for that, this device might not be the best solution for you. But everything where you only relate to high graphics power for example, an eGPU will help you with this (and will work with the V).
I cannot comment on the charging status light and the sliding capabilities.
