Isaiah Cartwright lead designer of the game Guild Wars 2 recently shared some information of the new levelling system developed for GW2. According to Cartwright the level cap will be 80, that is very high but with the new levellnig system the loops between higher levels will be decreased. In other MMOs when we reach, say LVL 50, it takes more time to gain XPs and reach the next level than in LVL 5 or so. That means we spend much more time on boring grinds in higher levels. So the time we spend on higher levels is exponentially growing but not in Guild Wars 2. The level curves of the game (see: here) is linear, so it takes the exact same time between level ups on every stages. Thanks to that, Isaiah Cartwright is confident that the players will forget about levels and time and the game will be much more enjoyable. To read more, check this site
